I think Moneyball tactics only get you so far. That's why the A's have never been able to take the next step. Moneyball strategies combined with the ability to spend money (ala the Boston Red Sox) will increase the probability of success greatly.
I think the success of the Red Sox is not so much in knowing what talent to bring in, but in knowing when to cut loose popular big name big $ guys, like Garciaparra, Pedro, and yes, Manny.
What I agree most with Moneyball is that batting average is the most overrated and useless statistic in baseball...next to earned run averages for individual relief pitchers.
