hwang-i think you are wrong.Watching zeller play d he still is thinking nor reacting,he is watching everybody else while adjusing position.The shuffiling of rotations and different players thrown together with no real quick point in the paint.This only his 3rd season,new coach and move.He is still young by big men standards and has the ability to bulk up.He has soft touch which you can't teach,how many bust 7 footers would you have to go through to find one that can run court ,play d ,shoot from outside and have that kind of left ,right flip hook.
