SeaWorld and the NFL

The orcas at SeaWorld are getting a new habitat. The new habitat will cost SeaWorld hundreds of millions of dollars and basically double the size of the habitat the orcas currently have.

Several events have conspired together to move SeaWorld toward building this habitat, but the catalyst can be traced back to a large male orca named Tilikum who murdered Dawn Brancheau, an experienced trainer who was working with him, in 2010.

A key point in the debate about whether or not “murdered” is an acceptable word for the events that transpired rests on whether or not any trainer at any level of experience is safe in the pool with an orca whale. In court, SeaWorld contended that trainers well versed in methods of animal learning and operant conditioning were perfectly capable of controlling a 3 ton whale. The Occupational Safety and Health Administration, on the other hand, contended that no amount of contact with orcas could be considered safe. After some legal wrangling, it was decided that any and all contact between orcas and trainers had to be done with a solid material, such as a concrete barrier, between the trainer and the whale. Direct contact was no longer allowed.

I’ve been returning to my feelings about the SeaWorld incident a lot during this week of terrible football fandom that just won’t end. I wonder about organized football, both in college and the NFL, from the perspective of a workplace. I think about the increased rates of brain damage, along with the recent instances of domestic violence, child abuse, and rape and I wonder what this game that I love to watch is doing to the individuals that get a chance to play it at a high level.

Last week I wrote about one of the great benefits to using statistical methods for employee selection. Basically, using math to find people means it is much easier to find other people should the ones you originally find not work out socially. That’s a great boon to employers in a typical workplace. They become less beholden to talent. Talented people no longer become insulated from the consequences of socially unacceptable acts. And, for any typical place of employment, that works quite well. However, I did not consider in that piece that the NFL is not a typical place of employment. Professional football has some troubling facts associated with it. As a psychology professor, I know all about what brain damage to the prefrontal cortex can do to an individual. Increased emotional reactivity and impulsivity are just the tip of the iceberg. I wonder if this game is destroying the lives of the people that play it. And I worry that anyone that works to identify and project success from one level of football to another, including myself, may be complicit in that destruction.

I am well aware that this blog isn’t particularly popular. As of this writing, I have 45 followers on Twitter and I get about 6 readers a day, 3 of which are spam crawlers. I am, at the moment, insulated from a looming ethical dilemma. No one with actual decision making power is calling me to learn my opinion on whether or not a particular player should be granted the “privilege” of continuing to play the game. The minute that happens, though, I will have an important decision to make. I will need to choose whether or not I should use my intellect to grant someone else the opportunity to potentially destroy theirs in the name of a sporting contest. I will need to decide if I believe the game of football can be played in a way that doesn’t destroy the lives of its players or if I believe my ability to identity talented football players is the same as placing the best trainers in a pool with 3 tons of socially maladjusted rage.

I do know one thing. Talking about football has never seemed more hollow than in these last 10 days. The heart-rune of my fandom is ripped. I’m not sure it will ever heal.

Beholden to Talented Shitheads: Why We Need Analytics

Categories: General Info, NFL

Published on: September 9, 2014

I hope everyone is enjoying the new football season. I’m glad to see the Vikings are 1-0 and the defense looked good, although, it was against the Rams so I’m not sure that means all that much.

I don’t have much to talk about in the way of numbers today. We’ve got one week worth of NFL data which will tell us largely nothing about how the rest of the season will play out and we’ve got two weeks of college football data which will tell us something so minor that we probably shouldn’t bother right now.

Instead, I thought I would talk about one of the more important social issues surrounding football right now. I want to talk about Ray Rice and, specifically, what Ray Rice shows us about the importance of adopting analytic strategies for selecting members of organizations.

Many people think that businesses use analytic strategies like skill testing and personality testing because the tests tell you which individual is the most talented, most productive, most useful potential employee and the business then selects the person who comes out on top of the most important tests. And if you think that, you’d be sort-of right about how the process works, but you’d also be sort of wrong.

Most businesses that use analytic strategies use their tests not to find a single individual, but instead to narrow the pool of possible individuals. Tests are used to cull the group, but they generally aren’t used to make a final decision. High scores are necessary to land the job, but they aren’t sufficient. Once the tests identify the proper pool of applications comes the next, and most vital question an interviewing team can ask, “Can we all work with this person?” Fit within the work culture and ability to get along with co-workers is critical to building a functional organization. Any business using this strategy needs to be very careful that their answers to whether they can work with different people are not biased in ways that violate Civil Rights laws or any moral principles that the company holds to, but in general that’s how companies use tests to select employees. Test them all, generate a pool, but don’t select based solely on high scores but rather on more human elements.

That’s the first way analytics helps you build your organization. You can be sure of selecting talented people that are actually the kind of people you want to work with. And that could be important if you’re trying to build a football team. Many coaches seem to have very high minded policies about avoiding players with domestic violence histories. And while they seem to stick to those principles to greater or lesser degrees depending on the talent of the player in question, we can at least see how this would work. If your analytic strategy returns two players as equally likely to succeed and one of them has a history of domestic violence, you probably go with the other one. But that’s not why NFL teams need to quickly adopt analytics.

Using analytics to select employees is critical when one of your talented and valuable employees makes a mistake so horrendous, so unspeakable that it makes you rethink whether or not you would be able to work with that person ever again. Enter our connection to Ray Rice.

What Ray Rice did was unspeakable. But how the Ravens and the NFL responded to the situation is just as unspeakable. And while I can’t speculate on what was going through Rice’s head when he committed his act, I have been associated with enough employee selection meetings to have a guess at what the Ravens were thinking prior to cutting him.

The Ravens, and all NFL teams, are in an industry where talent is incredibly difficult to identify. Highly trained NFL scouts get evaluations of talent wrong every season. It’s a terrible job to try to be good at because almost no one truly knows what it takes to be a great football player. If the organization can’t reliably identify talent, it becomes very guarded about the talent that has fallen into its lap. And when organizations have limited confidence in their ability to find new talent, they are more willing to forgive egregious actions from the talent they actually have. In essence, organizations can become beholden to talented shitheads.

Selecting players using analytic strategies can break that cycle. When a talented member of the organization moves into territory that the rest of the organization can’t follow, it is a simple matter to separate from that person, regenerate a new pool of potential applicants, and begin the selection process all over again. We don’t have to run our rationalizer ragged trying to find reasons why Action X might be morally repugnant, but doesn’t justify removal of the person from the organization. Instead, the incentives for talented individuals to act like a shitheads evaporate. The organization can afford to be less risk-averse when problems with talented players emerge. If the Ravens had a large scale analytics-based selection process they could have cut Rice in February and found two or three shiny new running backs. Instead, we have the nonsense we all saw this week. Honestly, I fail to see how the status quo is better.

Final NFL Pre-Season Projections

The NFL Season starts tomorrow.  As such, this will be my last revision of the preseason yardage projections.  To access the projections, either click on the link in the top banner or click on these links for


Wide Receivers

Tight Ends

A couple notes.

1)  Wes Welker is completely gone from these projections.  The news just came out that he’s out for 4 games due to some substance use, plus who knows how this concussion business will turn out.  Welker being gone actually helps Peyton Manning move into the top spot in yardage projections for quarterbacks.  Welker may be effective at getting you first downs, but he doesn’t do much for a quarterback’s YAC.  As such, we’re expecting Manning to get a few more yards with Welker out of the lineup than with him in.

2)  The Saints just resigned Robert Meachem (and surprisingly cut Ryan Griffin to do it).  Meachem has been a high quality receiver throughout his career, so his signing would be good news for Drew Brees.  He’s not on this list because there isn’t enough time to figure out where he finds a spot on the depth chart.  We will leave our conclusions about him to later in the season.

3) Very very very important to remember that the ability of this model to predict outsample date has not been validated.  We’re all going to be learning how this model does throughout the season.  Yay science.


NCAA Quarterbacks to Watch – 2014 Season

Published on: September 2, 2014

Week 1 of the college football season is in the books. I had intended to put together a post of the college quarterbacks I’m watching this year as NFL prospects. I did this last year and saw a lot of search interest in that poorly titled piece. Getting this piece out wasn’t near the top of the priority list, then the new semester started, I started working on a projection model for NFL production, and didn’t get around to putting out this piece until today. Sadly, this means I didn’t strike while the iron was hot in one specific case. I’ll take this as a lesson in timely publication.

Without further ado, the quarterbacks I’m watching for the 2014 NCAA season

Rakeem Cato, Marshall


Cato is still my leader in the clubhouse for NFL quarterback prospects. I actually thought he declared for the draft last year. If he had, he would have been my #3 quarterback prospect then. Things are looking good for him and I’m excited to see what he’s got during his senior season.

Brent Hundley, UCLA

Brett Hundley.jpg

The first player on our list that many scouts will likely agree on. He’s currently second on my list of prospects, but had a really poor game by his standards last weekend. I’ll be watching this one to see which way it goes. Keep watching the season numbers page for more updates.

Shane Carden, East Carolina

Here’s someone you probably haven’t heard of. I’ve said it before, but one of the best things about using numbers to scout prospects is the ability to find gems that don’t get a large amount of T.V. time.  And the numbers say Carden definitely is worth a long look from professional scouts. I think you’ll be pleasantly surprised by what you see.

Sean Mannion, Oregon State

Sean Mannion.jpg

Mannion apparently really impressed some people over the summer at a Manning passing academy. I’m glad to hear it because I’ve been watching him with some interest since the beginning of last season. Hopefully he can continue the trend and keep trending up. I’ll be excited to see where he ends up.

Brandon Doughty, Western Kentucky

Yeah yeah, I know. I’m four days late and six touchdowns short on calling this one. Lesson learned, I suppose. I should probably also note that with last weekend’s performance Doughty launched himself from fifth to third on this list. Keep watching this guy.

So there you have it. My quick list of who I’m watching this season. As always, season numbers are available on the top ribbon.

Quick Update

Nothing much new to report on the data front this week.  I updated the predictions for yardage totals recently.  The most important changes to the predictions are

1) Replace Sam Bradford with Shaun Hill as the Rams quarterback.  That change does not affect the predictions for the Rams receivers to a great degree.  My Twitter thoughts on the matter have not changed

What will change the predictions dramatically is getting some clarity as to who will get the lions share of the targets in St. Louis.  It seems as though the websites I access for information about depth charts have wildly different ideas about the Rams receiver depth chart.  This will probably update again before the season begins.

2)  Wes Welker completely removed.  I have no idea if Welker will come back or not.  The other day everything was “long-term health” and now today everything is “moving through the protocol.”  We’ll see, I guess.

2014 Passing Yardage Predictions – Part II

Categories: Fantasy, NFL, Statistics
Comments: No Comments
Published on: August 19, 2014

Welcome back everyone. I took last week off because some very important things were and still are happening in our country. I couldn’t bring myself to talk about a game overlaid on top of another game. It just seemed a little disconnected from the world at large. I think it’s important that we all stay reminded of the events happening in Ferguson, MO. That being said, it’s time to build an audience and nothing builds an audience like new content.

This week I finished a full set of projections for yardage totals of quarterbacks, wide receivers, and tight ends. This new model makes two major corrections compared to the one I posed a couple weeks ago. First, it corrects for 2013 injuries. You’ll note that Julio Jones has a much higher predicted yardage total in this model compared to the previous one. Second, it corrects for changes to the offensive system. I’ll get to why this is important in a minute. For ease of viewing, I’ve added a new page to the banner so you can easily check these tables whenever you need to. Remember that these yardage totals assume the player in question plays all 16 games and any coaches that have changed jobs do not radically alter the schemes they’ve used in the past. I also want to throw out a big thank you to Jeff over at for the offensive coordinator history spreadsheet that made all these projections possible.

One very important caveat before we begin. I don’t have any historical data to check these predictions against. Jeff’s data on targets doesn’t go back far enough for me to do any historical checking on how accurate this model tends to be. So, I have no idea about the uncertainty inherent in this model. We’ll all be learning this together as the season goes on. After the season is over, we’ll check them together. Isn’t science fun?

Top Projected Wide Receivers – Receiving Yards

My first list of projections is for wide receivers, and that list doesn’t come with a lot of surprises. You’ve got your Andre Johnsons, your Dez Bryants, your Brandon Marshalls and your DeSean Jacksons at the top. I don’t really see a surprise on that list until I see Josh Gordan predicted at less than 1,000 yards – assuming he plays all 16 games. And even that is understandable given Cleveland’s quarterback situation. I’ll keep the list updated as depth charts change and injuries occur.

Top Projected Tight Ends – Receiving Yards

Once again, a lot of ho-hum on this list. Jimmy Graham will lead the league in tight end receiving yards, a Detroit Lion will follow him because Detroit will still throw the ball all over the place and defenses will try to lock down Calvin Johnson, blah-blah-blah. You’ll see Levine Toilolo third on that list, but I’m not sure I buy that specific prediction. The model is assuming that Toilolo will step in and take all of Tony Gonzalez’s targets which my human brain tells me isn’t going to happen. I have left that prediction as the model reports it for accuracy’s sake, but on that one, I think we have some justification to adjust it down a bit.

Top Projected Quarterbacks – Passing Yards

I went back and checked the results I’m about to tell you three different times. As I was doing that, I anthropomorphized the mathematical equation and called it a “little dickens” for trying to trick me. But there was no mistake. The inputs I fed into the model were all correct. Furthermore, all the other top five quarterbacks make perfect sense. Most of us expect Carson Palmer, Drew Brees, Tony Romo, and Peyton Manning to have high yardage totals at the end of the season. But I didn’t expect the guy at #1 by a long shot. And so, without further ado, your projected 2014 NFL leader in passing yards – edging Peyton Manning by 98 yards – is…Houston’s Ryan Fitzpatrick.

You’d call a mathematical equation a “little dickens” too if it tried to trick you with such nonsense. After I saw it I looked up the prop bet odds on Ryan Fitzpatrick leading the NFL in passing yards and found that it’s such a ludicrous notion that Vegas isn’t giving action on such a proposition. It seems insane, but let’s keep an open mind and consider this for a second.

Once you think about it, there are several reasons why it makes sense that Ryan Fitzpatrick could lead the league in passing yards this year. First, we know something about what Bill O’Brien likes to do on offense. We know he likes to throw the football and his system is very effective at gaining yards through the air. Any system that makes Matt McGloin look that good has got to have something going for it. We also know that O’Brien provides a lot of opportunities to his best receivers and seems to be able to adapt the passing game around what he has. Second, Houston has the best receiving corps you will find outside of Denver or Chicago. From top to bottom, the wide receivers in Houston know how to get open and know how to get yards after the catch. This will be a second huge bonus to Fitzpatrick’s passing yards. Third, nobody really knows what the status of Arian Foster is. We know he’s busy trying to be the best teammate he can be, but can he still be the productive running back he once was? I have my doubts. And finally, I don’t want to count out the man himself. Fitzpatrick is a serviceable quarterback. He’s not going to take a team on his back or anything, but he’s not horrific either. There’s a reason he’s stuck around in the NFL so long.

So there you go. Lots of fairly boring expectations for receiving yards and one super out-of-left field prediction. Let the season begin!

2014 NFL Passing and Receiving Yard Predictions

Last time I broke down which rookie wide receivers and pass catching tight ends have the most talent. Now it’s time to get to the heart of the matter. In this post I will present a preliminary model that predicts total receiving yards for wide receivers and tight ends and total passing yards for quarterbacks. In the first pass through the data, I’ll be strictly using information from the 2013 NFL season. I’m not readjusting for previous injuries that kept a player off the field (e.g. Julio Jones & Reggie Wayne) nor am I readjusting based on the difference between early and late season play (e.g. Cordarrelle Patterson, though the opposite of what you’re probably thinking). I’ll make a more robust prediction once the depth charts are a little more settled.

To make this prediction I entered variables that represent quarterback ability (broadly construed), receiver ability (broadly construed), and number of targets into a Bayesian multiple regression analysis. If you’re interested in some of the technical details of the Bayesian analysis, they can be found at the bottom of this post. For the general reader, in the past, those variables have explained about 33% of differences in yardage totals and been off by an average of 300 yards. Also be aware that this model constricts the range of the predictions. It tends to underestimate the high end and overestimate the low end. The reason for the constriction can be found in the technical details.

The first table shows predictions for wide receivers. To get into this table, a wide receiver had to have been the target of at least one pass during the 2013 season and be listed as at least the 4th wide receiver on the projected depth chart according to CBS Sports as of July 24th. You can argue with me about that decision all you want. I made it entirely because I only have so many hours in my day and somebody else had projected some line-ups.

Couple weird things about this table. First is the insane yardage totals for both Antonio Gates and Ladarius Green. Green was very good last year in limited usage. Gates has been very productive for a very long time. The question for 2014 production among those two individuals is who is going to get the targets. Green’s prediction is driven by assuming great talent but limited targets. Gate’s prediction is driven by assuming many targets, but declining ability due to age. It will be very interesting to see how the tight end battle in San Diego sorts itself out. You’ll also see that one prediction is negative. The model is unimpressed with everything associated with Tennessee’s offense and makes no apologies for it.

32St. LouisSamBradford2534.0

Philip Rivers is the top of this list, largely because the model is unsure what is going on with the tight end situation in San Diego and is just sort of throwing up its hands. That being said, Rivers was really, really good last year and has an impressive cast to throw to. Antonio Gates and Malcom Floyd are quality veterans while Ladarius Green and Keenan Allen are up and coming rookies that had remarkable seasons last year. I’d be high on Philip Rivers.

That’s all for our first jump into predicting the 2014 season. Near the end of the pre-season, I’ll have a more robust prediction based on more accurate depth charts.

Technical details

The Bayesian model began with weakly informative priors. Receiver yardage totals follow a gamma distribution. In an attempt to simulate a long-tailed distribution, the dependent variable was assumed to be t-distributed. The equation was trained on data from the 2011 season predicting 2012 yardage totals and then evaluated with 2012 season data predicting 2013 yardage totals. Average deviation of the prediction from the actual in the evaluation data was 314 yards.

2014 Draft Class – Wide Receivers and Tight Ends

Summer time is over for us up here in the Deep North. Those two 90 degree days were brutal, let me tell you. I’ve spent the summer cocooned in my office cooking up the latest and greatest that I can offer in predictive football statistics both at the college and professional levels.

If you’re new to the site during a football season, I’ll be talking wide receivers and quarterbacks here, both at the collegiate and professional level.

And to start, let’s talk NFL rookie wide receivers. I made some predictions about rookie wide receivers for the 2013 season and they were…well they were terrible. I spent most of my spring and summer ripping apart the model and figuring out what went wrong. I discovered two very important elements of predicting wide receivers that needed to be addressed.

#1) What’s your Dependent Variable?

One of the trickiest things about doing football analysis is figuring out exactly what you want to measure and what you want your wide receiver or pass catching tight end to do. Many people have tried to deal with this issue when it comes to pass receivers with varied success.

My approach in 2013 was to use an in-house metric I created that measures pass catching ability. This, it turns out, was a horrible mistake. The reason is that NFL teams typically use particular wide receivers in particular roles. One receiver goes deep, another goes across the middle, etc. This creates a problem because it confounds pass catching ability with depth of target. Deep passes are successful less often, but the large impact they create on the game can offset their lower success rate.

For the 2014 predictions, I have changed the DV I use to get around this problem. I start with NFL Yards per Target. Yards per Target is much less susceptible to the depth of target problem. It’s not perfect, but it’s less bad than what I was using last year. I also do a little hoo-doo with the numbers to make them more consistent year-over-year. The first thing I do is to subtract the league average Yards per Target for the given season. This corrects for changes in the passing game across seasons, rule changes, passing tendencies, etc. Next, I use a highly constrained (sort of) structural equation model to pull out the effect of quarterback and offensive system on yards per target. I call it a “sort of SEM” because the model is incredibly constrained due to the realities of the game I’m modeling. It’s so constrained that what I do cannot be called a true SEM. But the technical details are probably not why you’re here. The ultimate result is a metric I call Receiver Influence on Yards per Target (RIYPT; in my ears “ripped”). We’ll use this metric at the NFL level as our DV.

#2) Lower-Level Interactions

Issue #2 I didn’t appreciate when making the 2013 predictions is the importance of interactions. You see, RIYPT at the NFL level predicts productivity. In fact, it’s the only receiver-focused metric that predicts NFL level performance. I made a bad assumption that the same situation would exist at the college level. It doesn’t. At the NFL level, every receiver has great hands. If you don’t have great hands, you don’t get to be a receiver in the NFL. Once we account for depth of target, there’s no meaningful variance in ability to catch a football among NFL pass receivers.

This is not true at the NCAA level. You can be a college receiver without having exceptional hands. As long as you make up for it with lots of long gains, less-than-stellar hands aren’t the handicap that they can be in the NFL. To deal with this, you need an interaction term. Interactions find the receivers that have good enough hands to make it in the NFL while also having the ability to gain useful yardage on an efficient basis.

That’s enough details. Down to brass tacks. Who should we be looking at as far as success at the wide receiver position? Remember, our DV is yards per target, so our definition of success may be different than the actual outcomes obtained on a football field. You can have a large RIYPT, but if you don’t get a lot of targets you won’t gain a lot of yards (see Ladarius Green in 2013).

The full table can be found above in the web page header. My top five rookie wide receivers, according to Predicted NFL RIYPT are…

  1. Brandin Cooks – Oregon State – 2.56
  2. Jalen Saunders – Oklahoma – 2.33
  3. Cody Latimer – Indiana – 1.99
  4. Marqise Lee – USC – 1.97
  5. Cody Hoffman – BYU – 1.93

Here you can see I expect Brandin Cooks to be head and shoulders above the rest of the rookie receivers in the NFL. This is especially true now that he is a member of the New Orleans Saints. Jalen Saunders will be a stickier situation. He’s a lower round draft pick, so it will be more difficult for him to see the field compared to Cooks. Second, he has (at the moment) Geno Smith throwing to him. Past visitors to the site will know I’m not high on Geno Smith. Geno will likely improve next year compared to 2013, but I still expect him to be in the bottom fifth of the league in terms of completion percentage and passing yards.

My top five pass catching tight ends according to Predicted NFL RIYPT are…

  1. Eric Ebron – North Carolina – 1.37
  2. Richard Rodgers – California – 1.12
  3. Marcel Jensen – Fresno State – 1.04
  4. Blake Jackson – Oklahoma State – 1.02
  5. Jace Amaro – Texas Tech – 1.02

Once again, we have one prospect that is head and shoulders above the rest, that being the prospect everyone expected to be on top, Eric Ebron. The second name on that list probably surprises a few people. If you look up scouting profiles of Richard Rogers, they’re not that glowing of him. I guess we’ll see where we end up. Rodgers also ended up in a great place to succeed as a pass catching tight end – Green Bay – so hopefully we get an opportunity to see him succeed.

This wraps up our rookie preview.  Up next, we’ll predict 2014 yardage totals for veterans from 2013 data.

2014 Draft in Review

This will probably be my last post before I go into summer hibernation to work on my receiver model. I was going to review the first round pf the draft, but that’s been done to death at this point. There isn’t much to be gained from rehashing all the details. Instead, I only want to talk about two teams, the Minnesota Vikings and Cleveland Browns.

Minnesota Vikings

Regular readers know that the Vikings are my team. They’re the team I grew up watching and the logo  on the blanket currently draping my couch. So when the Vikings traded up back into the first round, I reacted emotionally. The reaction was about the trade-up, not the actual pick itself. I was worried the Vikings had learned the wrong lesson from their experience in the draft last year.

Last year, the Vikings gave up a number of picks to move back into the first round and make a third selection in the first round. For doing this, they were applauded, given high post-draft marks, and given general kudos all around. The problem is that the actual move was a terrible one. And the reason the 2013 trade was terrible was the number of picks they gave up to make it. Every single credible analyst has shown that the way to get the most value out of the draft is to make more picks (see this new, inventive analysis showing how number of picks predicts total draft value). So the psychological problem is a problem of reinforcement. The Vikings made a move. In the short term, they were told that this move was a great idea. However, the negative consequences of the move they made will either never be realized because the Patriots rarely play the Vikings, or they won’t be felt for three to four years down the road, which is far too long to learn something from reinforcement. And not only that, but the Vikings got incredibly lucky that their target in the trade up is showing promise as a wide receiver and kick returner. All this is positive reinforcement for making a trade up more likely in the future.

I was worried that the Vikings had learned the wrong lesson from their experience last year. I was worried they were going to give up a two to three picks to move back up into the first round as they did last year and then not recoup those picks in the later part of the draft. I’m very happy to say I was wrong. At the end of the draft the Vikings had made, by my count, the 4th most picks of any team in the draft. That’s a path to success through the draft if ever there was one.

As for the actual pick itself, I don’t mind the Vikings picking Bridgewater. My model isn’t precise enough to get upset about a difference between a predicted passer rating of 80 vs. 75. Good luck to the Vikings in the 2014 season.

Cleveland Browns

The Cleveland Browns are run by Blitzwing from Transformers: Animated. If you don’t know Transformers, Blitzwing is a triple-changer. He has forms of a jet, a tank, and a robot. To drive home the “triple” metaphor, the character has three distinct personalities. One of them is cunning, cold, and calculating, one of them is emotional and explosive, and one is completely wack-a-doodle. Or, as my 4-year-old nephew named them, Smart, Dumb, and Scary.

 photo blitzwing.jpgAny move the Browns make seems to fit into one of these three categories and you can never tell which personality is going to be in control for any specific decision. They achieve great outcomes, but project this image of ineptitude. They do really smart things to set up the situation in their favor, but then bungle the execution.  You could do Homer-Buying-the-Cursed-Krusty-Doll for an entire day with this team.

They commissioned a $100,000 study that (supposedly) said Bridgewater was the best quarterback in the draft.

That’s good!

They released the results of that study before the draft.

That’s bad.

They entered the draft with 10 selections.

That’s good!

They ended the draft selecting 6 players.

That’s bad.

They traded down with the Bills and secured picks in future drafts.

That’s good!

They gave up a pick to move one spot up.

That’s bad.

They selected Manziel with the 22nd pick.

That’s good!

They outbid three other teams to trade up to get there.

That’s bad.

They signed Joe Haden, one of the best DB’s in the league to a big contract.

That’s good!

They also signed Miles Austin, a 30-year-old, oft injured wide receiver who hasn’t been productive since 2010.

That’s bad.

But he came with a free frogurt.

That’s good!

The frogurt is also cursed.

Can I go now?

How can a franchise make such good decisions at one time and such bad decisions 15 minutes later? Being run by a robot in disguise with dissociative identity disorder is the only possibility I could come up with.

Spaghetti & Advanced Analytics

Published on: March 12, 2014

For being a German-Russian/Norwegian from North Dakota, I make one tasty spaghetti.  Cooking is one of the few hobbies that I get to indulge with my academic career as it’s difficult to claim that one is too busy to eat.  If you come to my department and ask my co-workers, they will tell you that they’ve all heard about my fabulous spaghetti.  I’m getting the feeling that they’re all getting a little tired of hearing about it without getting to eat any of it.

Now imagine I invited you over to my house for spaghetti.  Or rather, that I told you I would make my spaghetti for you if you would be willing to pay for all the ingredients that go into it.  You’ve heard me boast about my spaghetti.  You know that I talk about the time and care that goes into my spaghetti.  You decide that you are so intrigued that you’ll put down some cash to finally get the privilege of eating this wonderful spaghetti.  You might even start imagining what you’re going to get on the way over.  What could be in this oh-so-hyped spaghetti?  Is it a secret, homemade sauce?  Basil-infused deep-fried meatballs? (Sidebar:  mmmmm…basil-infused deep-fried meatballs)  You won’t know until the meal is prepared, but you’re thinking it must be something good.  Finally, the spaghetti is ready and I drop this in front of you. What would your reaction be?

At best, you’re justifiably annoyed.  At worst, you would curse my name and flee the house, using very forceful language about how much you’d rather be at Olive Garden right now.  You spent good money on something that a college sophomore creates every other day.  Beyond just being upset, you want to make sure that you never get tricked like that again.  What’s your solution?  How are you going to make sure you don’t get bamboozled into buying buttered noodles from a fast talker again?  The solution you propose is important because it calls into question the nature of proprietary knowledge and could ultimately dictate the ability of restaurateurs to make a profit on their business.  Do you want me to open the kitchen next time and show you how I made the spaghetti?  Do you simply not trust anything I say ever again, even after I’ve learned that buttered noodles are not what the rest of the world would call “tasty spaghetti?”

But I’m not a restaurateur (even though that spaghetti is really good, you guys).  I am an academic.  In my professional life, I don’t have a restaurant, but I do have research ideas that could get funded and pay my salary.  I may not have spaghetti, but I do have a model that predicts professional level success from college level inputs.  But I didn’t create the model to be exclusively about football.  It could apply to any interdependent situation.  Football just happens to be an interesting place for me to apply certain ideas.  The fact that the “field” of “sport analytics” is a growing area of interest is also nice because it makes it easier for me to spread interest in my research.  The more people that are interested in my research, the more valuable my ideas are, which means I could eat and pay my mortgage thanks to said ideas.  However, sports analytics as a field has a problem.

About 10 days ago, about 2,000 sports executives, academics, and analytically minded people all took a long and expensive trip to the Sloan Sports Analytics Conference in Boston.  They went there, by many accounts, for the express purpose of not talking to one another.  Sure, conversation was had, jokes were made, papers were presented, and libations were served but by all the accounts I’ve read or listened to nobody officially talked “spaghetti.”  Which is ultimately the problem that sports analytics is developing.

In a competitive environment, having knowledge that no one else has confers an advantage.  Sports teams have picked up on this notion and begun to make their data, their data analytic tools, and their methodologies private and proprietary.  The message to people like me is clear:  Unless the process is secret, it isn’t worth much.  This is a problem for me as I would very much like to use my brain to get money to eat.

So here I sit, not quite sure where to go.  I have no incentive to give anyone details about the methodology, but won’t gain any credibility until I do.  This blog hasn’t particularly taken off in popularity.  I’ve tried to publish my methodology in academic journals but gotten three rejections, two of which were “Well, we think this is neat, but it’s not really a fit for our journal.” And I can’t exactly take it to a football team because 1) only secret knowledge is valuable and 2) NFL teams are not particularly incentivized to adopt useful advanced statistics in the first place.  Given this environment, exactly what is a quant to do?
