One of the arguments in the BP piece really gets to me. I think there is an assumption that completely ripping apart and rebuilding is the obvious stategy. It's window dressing, while the core strategy is drafting and development. Also, I think the rip apart/rebuid mode comes with some risk. Lots of teams seem to perpetually be in this mode. The Pirates, Royals and Orioles immediately come to mind. Being really crappy seems to create an undertow that can be hard to escape.
My main point is that in 2013 on, the prime determinant in the quality of the Astros will not be who they got for Oswalt, Berkman, or Myers, but how well they drafted and developed players from 2008 on. People always fucking criticize Wade for this or that, without even mentioning how he is doing on his most important responsibility. Similarly, the recognition by Drayton a couple of years ago that player drafting, signing and developing is important is far more significant than his realization that the club might be years away.
