I think 3pt shot is the easiest target so most people talk about that one. I don’t totally disagree, however he ended up shooting .375 in conference play which is good (small sample). He started knocking them down towards the end of the year.
So along with 3pt shooting, I would say some sort of floater type shot, better decision making, and better finishing at the rim (he missed some bunnies).
A lot of that I think he gains with more minutes, the question is how many minutes is he going to get this year with Jbo coming back. I hope he gets at the very least 20 minutes a game.
