I think the Robinson-Sullinger comparisons in this thread are a little confusing. They have similar length, play super physical, and both have beastly rebounding ability. Otherwise, they don't have much in common- the rest of Sullinger's game is his skill and finesse and the rest of Robinson's game is his quickness and bounce.
Someone asked what Robinson does better than Sullinger. The answer is that Robinson can play above the rim, he is a far better defensive player (or at least he would be on a reasonably coherent team), he can get out in transition, and he can sneak in a little dribble drive here and there. He also comes without any back issues or weight problems.
Well, they have one other thing in common- they both look like they could grow into dominant NBA bigs. Sullinger's ceiling is Al Jefferson whereas Robinson's is Blake Griffin.
So... who doesn't want two of those on their team???
