Willie Cauley-Stein will bust IMO...
I'm higher on Okafor than most, people knock his athletic ability but he's super long, rattles the rim with standing dunks, runs the floor well he's a better athlete than giving credit for. It was the same thing with Jabari Parker and he ended up killing the combine and was arguably the most explosive rookie before his injury.
Okafor is too skilled to not draft number one he's toying with guys in the post he's a more athletic Al Jefferson with better passing.
