You way overrate him, hes not as athletic as Dwight in his Prime or as strong as Shaq. Sure he has his post moves, they seem to be as good as DMo's. But thats about it. I have no doubt that at his peek he will probably be able to have 22pts 13reb seasons. But NBA is full of amazing players, which are already rated much higher than him and they are playing on way better teams, it prolly take him good 3years of playing just to get to PO's..
Okafor looks great in the popst, excepting for one thing: he somehow plays below the rim, despite being 6'11. He doesn't play with any vertical.
