Robert Williams will be drafted higher too. Nowadays centers in the mold of Enes Kanter(haven't seen McCoy yet, but that's the impression I'm getting from what people say, is this wrong?) are not as valuable as they used to be. What teams are looking from their centers is defense-first, rim protection and rim rolls. Of course other things are nice to have but if you don't have the defense as a center you are almost unplayable against good offensive teams.
Yeah, I said Williams in the 4/5 tweener category.
