I'm not... there is obvious concern with his shooting.... not just that it doesn't go in but IMO he clearly lacks confidence in it and is passing on shots he needs to take. And despite all that, I still like him the best from all the prospects I've watched so far and I do think there are reasons to think he will improve his shooting(form looks good and repeatable, FT% is solid, work ethic and attitude)
Personally, I think the lack of confidence is not exactly a good sign. It's a chicken/egg kind of problem, but I will say that poor confidence probably comes from poor shooting more than poor shooting comes from poor confidence. I do think he has great work ethic, but that is also a double edged sword because his great work ethic/elite mentality has not resulted in a jump shot....yet.
I also really like him, and I think he will find a way to become an effective player even if he can't shoot....but the shot is a true limiting factor for him. Given this poor draft, he's in the top 5 or close to it for me though.
