I would have two issues:
1: His shooting range is very poor, with him and Biz teams would be able to just let them go out the paint and leave them free while packing the lane. This would make it harder for Kemba and MKG getting inside.
2: It was visible all season that guys who were bigger and stronger than him limited his effectiveness, in the NBA that is going to be pretty much everyone.
But then again I do agree with all the points you said, it's all a question of how everything translates into the NBA... Anyone have a crystal ball?
