Tubby will not reward Iverson for good play
Sampson is one untouchable starter. I see one main area Sampson is better than Iverson in, that is moving his feet on defense: pick and roll defense, or guarding a face up player. I'll even give you a slight edge as a passer and outside shooter, but it is small.
Iverson is better at rebounding, boxing out, finishing, setting picks, getting physical. Over the last 8 games Iverson is the much better player. I do not think he will get the mintues, we know he won't start. If we get trevor or another power forward I would assume that would cut into Iverson's time, not Sampson's.
