He's definitely upped his defensive game, a part of him that was good but is noticeably more aggressive this year. On the offensive side of the ball he's still chucking it up from outside and only shooting 33% from there. For a senior his FG% and 3P% shouldn't be trending down like they have every year since his Freshman season. If he was being asked to do something different on offense I haven't seen it (his assists are down ~50% but his rebounding is up ~10% from last season).

He's great at one end but a liability at the other. Maybe it's just his focus on D that's taken away from his need to clean up his O?
