I'm really not sure how much of an nba player he could have been. I mean, he never really showed much. I think at the time people were just amazed by the fact that he was a 7 footer with the skills of a SF but it's not like he was Lamar Odom. He didn't have perimeter skills and big man skills. He was really just a decent scorer who happened to be tall. When he was on the court he didn't block shots, or rebound, or defend. I don't see him becoming an nba rotation player unless he has put in quite a bit of work on those things that he was never good at.
well he never showed much because 1) he was drafted right out of high school, so it's understandable that his first couple years he wasnt putting up great numbers and 2) injuries. He didn't have handles like odom, but he still had decent handles and a pretty decent outside shot...if memory serves, he was in the dunk contest and 3 pt contest in the mcdonalds all american game bottom line, he had a ton of potential but injuries held him back.
i hope he succeeds. i cant ever think of him with out thinking of judd nelson's jon bender from the breakfast club
