I watched him play on ESPN2 last night.
He didn't look any different from Kwame Brown or Tyson Chandler to me. He's about 6'10" or 6'11"...thin, well-built and athletic. He showed a neat little hook shoot in the post...he dribbled fair enough if not smoothly and he had an awkward jump shot.
He let the other center (a 6'11" kid who was strong but not nearly as athletic) beat him up and dunk on him a couple of times. He didn't really have a nose for the ball. He did a couple stupid things like trying to take the ball up himself with the game on the line and running over another player to get the offensive foul called on him. He also seemed to have a bizarre tendency to go inside against the other big man and to stay on the perimeter against the little guys. He only scored 19 or 20 points overall.
He reminds me a lot of Marcus Camby and Tyson Chandler. He showed no real face-up game to speak of...but a few good post moves and athleticism. Like Chandler...he also showed little heart or competitive fire. He might not like basketball that much.
He'll be drafted high...but there's not much reason to believe he'll be better than Chandler or Kwame. No way I'd draft him over Okafor. Maybe 4th or 5th.
