Paul DePodesta Quotes in Moneyball
Chapter 2 Quotes
There was, for starters, the tendency of everyone who actually played the game to generalize wildly from his own experience. People always thought their own experience was typical when it wasn't. There was also a tendency to be overly influenced by a guy's most recent performance: what he did last was not necessarily what he would do next. Thirdly—but not lastly—there was the bias toward what people saw with their own eyes, or thought they had seen. The human mind played tricks on itself when it relied exclusively on what it saw, and every trick it played was a financial opportunity for someone who saw through the illusion to the reality. There was a lot you couldn't see when you watched a baseball game.
In this chapter, we’re introduced to Paul DePodesta, the man who used a sabermetric player acquisition strategy for the Oakland A’s during their 2002 season, rather than listening to the advice of talent scouts. DePodesta came from a sports background, but he’d also studied economics, and he realized that, by studying an athlete’s overall record of play, general managers could identify players for their holistic talent and get a good idea of how they’d perform in major league games. Before 2002, the Oakland A’s had sometimes used a limited sabermetric approach to player acquisition, but this approach had always been balanced out by the strong influence of old-fashioned talent scouts.
As the passage suggests, the management of the Oakland A’s was severely set back by the scouting system—in particular, three main sources of bias. When trying to identify good athletes, talent scouts ignored statistical record altogether—instead, they trusted what they saw with their own eyes. The athletes they selected had to wow them with big, impressive plays and, ass a result, scouts sometimes neglected steady, reliable players who ultimately performed better as professional athletes. Paul realized that by eliminating bias from the scouting system—trusting the numbers instead of his own senses—he could assemble a formidable baseball team while also saving a fortune.
"He's the only player in the history of the SEC with three hundred hits and two hundred walks," says Paul, looking up from his computer.
It's what he doesn't say that is interesting … He doesn't explain why walks are important. He doesn't explain that he has gone back and studied which amateur hitters made it to the big leagues, and which did not, and why. He doesn't explain that the important traits in a baseball player were not all equally important. That foot speed, fielding ability, even raw power tended to be dramatically overpriced. That the ability to control the strike zone was the greatest indicator of future success. That the number of walks a hitter drew was the best indicator of whether he understood how to control the strike zone.
Chapter 12 Quotes
"I made one decision based on money in my life—when I signed with the Mets rather than go to Stanford—and I promised I'd never do it again." After that, Billy confined himself to the usual blather about personal reasons. None of what he said was terribly rational or "objective"—but then, neither was he. Within a week, he was back to scheming how to get the Oakland A’s back to the playoffs, and Paul DePodesta was back to being on his side.
