I think his achilles heel was shown last night. Did you notice how much he struggled with the trmendous athletes on the Kansas squad? Their speed and jumping ability seemed to catch him flat footed. He was out hustled to rebounds, beaten to the loose balls, had his shot rejected several times, and just looked slower than his counterparts from Kansas. And even his great heart and effort were not enough to cover the difference. Now, when you take into account that the NBA players are even better, that is what will hurt him.
With his ability inside and the nice mid range jumper he possesses, he wil still likely go late 1st or very early 2nd. He will be a good bench player for 15-25 min per game, and will have a nice NBA career I hope. But, the liabilities were really spotlighted by Kansas, and you can only imagine that an NBA team would know exactly how to handle him.
