He is a special, special talent. Not clear why to me the draft sites are ignoring him, but NBA scouts are not. He will contribute to an NBA team from day 1 & teams that bypass him in the draft will regret it.
He does push the envelope from time to time (heat checks etc.) but when he is on like tonight, the team needs that from time to time. His sub-par games have been few and far between (Stanford, Cincy and IIRC SMU) and sometimes only a really bad half (see 1st Houston game) but have accounted for 4 out of 5 losses.
