moneyball was NOT about simply exploiting inconsistencies in the market of baseball. It WAS about OBP, and that it's undervalued. if teams had undervalued defense, he wouldn't have exploited THAT incosistency, because undervaluing defense is not really exploitable, defense isn't nearly as important as OBP. Billy Beane was able to find that the single most important conventional statistic in the game of baseball (also referred to as "outs NOT made") was also it's most ignored. Sulley, what abou this quote from Beane from 2004? "BB: Exactly, guys like Scottie Hatteberg. Now people are recognizing the value of that and they're paying for it. And if we're in a bidding war, we're going to lose that. So we have evolved. If you look at some of our first playoff teams, the `99 team that won 87 games, it was a power, on-base team. Now we're tops in the league in defense and pitching. For us, it's all about filling in on the backend and figuring out what people are undervaluing. You know, one day we're going to have a team with guys who steal 50 bases because people aren't paying for it. But it's all about wins. That's all that matters." It certainly sounds like he has gone after some defense since it was undervalued, and would do the same thing with speed. Beane is willing to exploit any inconsistency in the market, not just OBP. By the way, here's the link on that-it's about halfway down. http://www.athleticsnation.com/story/2004/9/20/23544/2604
