Well for one thing, having a gaudy list of hitting prospects is great, but not all of them are going to turn into good major league players. And among the ones that do, most aren't going to be real plus players for at least a year or two, maybe more. I don't think it's a good idea to pin all your hopes on these guys panning out, not to mention giving them no veteran protection. Stockpiling is smart - it gives you options when the can't-miss prospects miss. But some of them will miss. This. I kind of want to make sure we hit on enough prospects out of the Bryant-Russell-Baez-Shwarber-Alcantara-Soler-McKinney-Almora group before we start shipping any of them or Castro out. I don't know, maybe that's a tad conservative, but I'd hate to stockpile all this talent just to guess wrong on which of them are actually going to pan out. I'd like to let these guys develop for at least another year (i.e. next trade deadline) before we start spinning them off.
