The core moneyball idea, for me at least, was identifying an undervalued potentially winning strategy with the help of data and then using data to identify players to best cary out that strategy. Interestingly, in baseball, the A's are back to a homerun hitting strategy because moneyball caused their original strategy of getting on base to become overvalued, leaving other market opportunities. So avoiding homeruns wasn't really the core idea. And it should be noted the As have never won with this strategy. They won with steroid taking supermen.
