They should expand the NBA Dunk Contest to 6 participants next season and then have these guys compete
Nate Robinson
James White
Josh Smith
Gerald Green
Andre Iguodala
Tyrus Thomas
If that wouldn't be a dunk-off for the ages, I don't know what would.
Also, in Slam Magazine in 2001, James White made the following statements as a high-school senior "Vince Carter is the only man alive who can out-dunk me" and "I only lost the McDonald's Dunk Contest because you couldn't have props, which takes away like half my repotoire".
He also lost the NCAA Slam Dunk Contest earlier this year because he mucked up from the free-throw line too, but he was definitely the best competitor on the day up until that point.
Come to think of it, I also doubt he'll be a good dunker in traffic. I mean, he's 6'7" but only 190lb, compared to a 6'6" 225lb Vince Carter, so he'll need to add some bulk to hang with the big guys. I still think he'll be just as exciting as Carter out on the break and in the Dunk Contest.
According to NBA Draft.net, he'll go at #39 to Milwaukee. It also says there he rates well as a passer and defender, but an bit of a dodgy jump shooter and not assertive enough on offense
