Kid can dunk well. Dunking is but a small part of the game and once you can do it, its rather easy. But for those who can't they think its the greatest thing since sliced bread.
I know it's easy to reduce him to dunks thanks to ESPN, but if you actually watch him play a bit, he has a really good mid range jumper, can hit a three on occasion, though he certainty shouldn't be gone to for that, and has a pretty solid low post game.
He needs to improve on one-on-one post defense, but what rookie doesn't and he is already an above average help shot blocker. He also rebounds at a high rate both offensive and defensive
He also has a bit of that "I'm going to rip your head off" mentality on the court that makes him extra dangerous
To pretend he's just a kid who can dunk is to not understand the player.
