Fine. And lets say while Youk was on the DL, Crawford hit 2nd and came out and hit .330/.370/.450 for 2 weeks. You wouldn't consider leaving him there and altering the line up? You wouldn't want to take your .250 hitter and turn him into a .310 hitter by moving him to the 2 slot and basically telling him "Hey. We have confidence in you, we know you're better than this. We're going to keep you here so you're comfortable and can keep it going"?
You sacrifice what, dropping Pedroia to 3, Gonzo to 4, and Youk to 6? Youk is having a pretty sub-par year anyway, and the guy can't hit on the road all of a sudden. It would be extremely beneficial to at least see what Crawford could do in the 2 slot when you've got your 2 hole hitter in the 4 slot.
