This year we are going to need his scoring, he has an off game of say 6 points against a good team and Duke probably isn't gonna win. I don't expect him to be a great defender, but if he fights hard that should be enough, he does do a good job of staying in good position defensively, and that's half the battle.
He should get stronger, and his strength should really help his rebounding. He's naturally a great rebounder, he just couldn't do much last year due to strength issues. I expect some 20 and 10 games out of him.
