Right. What people always seem to forget about the analytics based approaches, particularly the "moneyball" concept is that the intent was to identify those undervalued players. If the current trend is to prefer players with attribute X, that means that they'll be more expensive than their relative worth, so identify attribute Y which is also important and you can pay them a lot less. People still refer to moneyball style approaches as if the exact metrics which were used in 2001 are the end all be all, but as soon as people caught on to OBP and such the real moneyballers were by definition off to something else.
