I do expect AE to be the go-to guy in crunch time, but we need to have several other weapons cuz they will get open looks when he is doubled. AE will be a much better prospect if he moves constantly without the ball, sets screens, finds open guys. The development of our other players (particularly their shooting skills), and their positioning and movement, will lessen the defensive pressure on the Ant.
I haven't followed Crean teams much, though the performance of the Marquette team when they had D Wade gives me some hope that the Coach knows what he's doing. Dwyane was a superstar, but he was not a ball hog.
