It seems to be a case of him dominating children in high school since he was a physical beast. Dude looks like he's 30 years old and he's 19. I remember watching his highlights when he was the #2 prospect in the class and thinking that he didn't look that good. Also, if you guys think Portis sounds dumb, go listen to Cliff Alexander's interviews. He blames Coach Self for not playing him, he says that in the NBA you can expect to see "high school Cliff Alexander" type domination (if he couldn't dominate college players, how the hell is he going to dominate NBA players?). He also said in 5 years he "hopes to still be in the NBA" but also compares himself to Amare Stoudemire all the time. Before the season they asked him how long he plans to stay in college. Usually people just say "I'm gonna play hard and whatever happens happens" and Cliff just says "One year. Two years at most."
In his latest draft workout vid his footwork looks awful, but his jumper looks pretty good. If he can shoot the midrange consistently and learn how to play smart, he can play in the NBA. That is a big "if" though. The game moves so fast for him and he doesn't make smart decisions on the court. He's definitely a very high risk, high reward prospect, so somebody will take a chance on him in the second round.
