Our old friend Moneyball will be making a comeback this year, when the film starring Brad Pitt gets released this September. Let me declare seven months ahead of time that I am sick of hearing about how the movie hype is distracting the 2011 A’s during their pennant run. I am also preemptively tired of the rehashing of old arguments, such as how the A’s philosophy failed because the Moneyball generation never won a ring. Finally, I am, in advance, savoring the irony of the A’s winning the 2011 World Series, in the very year that this antique anti-Moneyball argument reaches its crescendo.
I love me a good irony. I took my daughters Monday to see Sally Ride give a speech for the UC Berkeley Physics Department. I looked around the auditorium and noticed that darn near everyone in the room was skinny. Maybe these people burn all their fat off just by thinking so hard about the universe. Whatever the cause, I found myself tickled by this ironic idea: Physicists have very little gravitational pull.
The irony that lies at the core of the Moneyball book is that A’s GM Billy Beane was trying to find a way to weed out players who were essentially just like himself. Beane is a very intelligent guy with an chiseled athletic body whose intelligence got in the way of his performance. You look at him, and you think he was born to be a star athlete. But he never became one. He’d get so worked up about every little failure that his swing and approach got all screwed up. He couldn’t handle the mental part of the game.
So Beane became a scout, then a GM, and tried to come up with a reliable way to weed out players like himself who can’t handle the mental part of the game, and discover the players who can. They tried to accomplish this by using a deeper understanding of statistics.
Which is odd, if you think about it. It isn’t the players’ statistics that are causing players like Beane to fail. It’s their brains. If you really want to be able to recognize players like Beane in advance, shouldn’t you try to do this with a deeper understanding of brains?

We are living at the very dawn of neuroscience. In the last ten years or so, our understanding of our own brains has exploded, and we’ve still only scratched the surface. Consider this TED talk by Charles Limb:
Limb explains what happens in the brain when jazz musicians improvise. When improvising, jazz musicians shut off a part of the brain called the lateral prefrontal cortex, which is involved in self-monitoring. They literally turn off the inhibitions in their brains, so they aren’t afraid to make mistakes, and are free to be creative.
Now it would be a big leap to say that Billy Beane’s mental failures were caused by an inability to turn off his lateral prefrontal cortex while batting. But it’s not a big leap to think that this sort of understanding of the brain isn’t just possible for musicians, but for athletes, as well.
Someday, perhaps, draft preparations will include brain scans, so teams can see that a Billy Beane’s brain isn’t focusing properly when batting. They’ll know how often you can take a player with Beane’s brain profile, and train him to overcome those brain issues. They’ll discount or increase his value because of this information.

In Sports Illustrated this past weekend, Joe Posnanski looked into the question of how drafting teams can predict which quarterbacks will succeed in the NFL, and which will fail. In particular, he wonders what set Aaron Rodgers apart from other first round QBs who flopped. He makes a guess:
What you get from these quotes and just about everything Rodgers says — in addition to steady and pleasant boredom — is a sense of someone who thinks about things constantly, even little things that few others think about. He seems to be someone who simply cannot imagine staying the same, simply cannot imagine that he’s already good enough. There are so many potential distractions at the NFL level, some of them off the field (money, fame, fan fickleness …), some on the field (dealing with pain — Rodgers has a history of concussions — standing up to a heavy rush, the inner workings of a team …). And the most successful quarterbacks, bar none, are the ones who deal with those distractions and never believe the hype and continue to hunger for even the slightest improvement.
To which I ask: how does this separate him from Billy Beane the baseball player? Beane thought about things constantly. He obsessed over every failure, trying to fix every mistake. And this sent him into a downward spiral that made him worse and worse, not better.

I like Zito. If not for the early Cy Young Award and that ridiculous contract, he’d be the kind of underdog people like to root for. Posnanski’s phrase “continue to hunger for even the slightest improvement”: that’s Zito. He’s a smart guy. Curious. He likes to tinker. To experiment. To find a new way to get better. He tries new pitches. He tries new pitch sequences. He tries new release points. And maybe that constant search for improvement has kept him healthy and pitching in the major leagues for a decade with the mediocre-est of fastballs.
But I’d argue that perhaps as often as it’s helped him, that personality trait has gotten him into trouble. Zito has had three pitching coaches in the majors: Rick Peterson, Curt Young, and Dave Righetti. Pitching coaches tend to live by a sort of Hippocratic Oath: if it ain’t broke, dont’ fix it. Zito doesn’t seem to believe in that. Each time there was a transition between coaches, Zito decided to take advantage of his temporary lack of parental supervision to completely change his pitching motion.
In 2004, Zito decided to try a new motion out of the stretch. He’d always wanted to do this, but Rick Peterson wouldn’t let him. When Curt Young came in as the new pitching coach, he didn’t have the relationship with Zito to say no. Zito had a 4.48 ERA for the year, his worst in an Oakland uniform. The next year, he was back to his old delivery, and his usual sub-4.00 ERAs.
In 2007, he signed a huge contract with the Giants, and showed up at spring training with a radically new delivery. Pitching coach Dave Righetti was horrified, and they settled on a compromise semi-radical new delivery. The results were just as bad as the other time he tried to overhaul his delivery: Zito’s worst year in the majors, a 4.53 ERA. (Followed the next year by an even worse 5.15 ERA.) Two years into his Giants tenure, Zito finally tinkered himself back into some decent success, with two consecutive years now of ERAs around 4.10.

Recently on Fangraphs, Jonah Keri suggested that the Yankees try to trade for Zito.
I don’t think there’s anything particularly wrong the arguments he gives, but it is, like the Moneyball story, missing the psychological element.
Psychology clearly matters in the outcome of sports careers. The question is, understand enough about sports psychology that such data points are useful in evaluating players, or is the information we have so primitive that we should discount such information altogether?
The Yankees are unique in that they also deal with the theory that there are some types of personalities who “can’t handle New York“. This theory may or may not be valid, but I’m willing to consider that it is possible.
I’m not going to come out and say that Barry Zito is another Ed Whitson. But New York media pressure or not, we do have these data points: each time Barry Zito has had a change of scenery, he used the opportunity to make a royal mess of his delivery.
I think if you’re Brian Cashman, and you’re thinking of trading for Barry Zito, you should know these data points. There is a non-zero risk that Barry Zito’s brain is going to get in the way of his performance, because it seems to have happened to him before. And there’s a non-zero risk that the New York media pressure will trigger this effect, because it seems to have happened to other players before. And to the extent you’re willing to believe those risks exist, you have to discount Barry Zito’s value.

In Billy Beane’s case, the constant striving for improvement was nothing but counterproductive. In Zito’s case, we see some mixed results. So even though it’s a different sport and a different position, I have a hard time believing that the key to Aaron Rodgers’ success is simply a matter of willpower, that same constant striving for improvement.
If I had to guess, a quarterback’s success involves spacial pattern recognition, the ability to quickly recognize types of player movement, to filter out inessential patterns and recognize significant ones, and act on them. Maybe some players filter out too much information, and others not enough. Maybe there are places in the brain that Aaron Rodgers turns on or off in better ways than the quarterbacks who failed. Those places are mostly a mystery to us now.
But they won’t be a mystery forever. A new era is dawning.
