And you'd be wrong.
Moneyball is the art of finding what player in MLB is undervalued at the present moment, and building a team around that concept. OBP was undervalued in the mid-90's. Beane built a team around that. Defense was undervalued in 2004, Beane built a team around that.
Besides, tell me once again why walking is a terrible thing to do?
Devil Rays - .312, 29th in runs scored
Cubs - .320, 30th in runs scored
Pirates - .329, 28th in runs scored.
It's not a geeky thing anymore. The more you get on base, the more runs you scored. It's that simple.
(Also, quit being a moron and throwing Dave Roberts out there. If Dave Roberts played for the A's, he'd steal 30 bases. The A's send runners, but only those who are good basestealers. Read the damn book, then make an argument.)
