He's a wing, not sure why rebounding matters much at all given the possible major flaws of the other top 10 guys. He's averaging 7.0 reb/40.
I don't think anyone's really drafting him to become a 20 ppg scorer in the NBA, though he could possibly get there. He's averaging 16.6 ppg on a top 5 offense in the country, despite having two teammates with a higher USG%. He can shoot off the catch, get to the rim fairly well, and get buckets off pure hustle.
Also, earlier in this season Mikal struggled with creating off the dribble, and that's just gotten stuck in peoples' heads. Yet I think he's made strides in that facet of his offensive game. And of just about anyone in this draft, I would trust Mikal more than anyone to continue to improve his game year over year. And that's not even to bring up his defense, where he may be the most versatile guy on that end in the entire draft.
