20 year old offensive D, playing 23 minutes a night in his rookie season. He's going to make mistakes on the defensive side of the game. And as a rookie he really isn't bad at all. He's been pretty good. Plus, he more than makes up for it on the offensive side.
As
@Lafleurs Guy mentioned,
I don't think i've even seen a playing style like his. He is incredibly deceptive and shifty. I never expect what he's going to do, and I have no idea how he manages to create space where there is absolutely none.
In theory, he should only get better as he adapts to the game.
