I wouldn't say elite... I think the eye test and percentages tell me he will shoot it. I think the lack of catch and shoot opportunities is indicative that his situation kind of sucked and if he had more opportunities there his percentages would be better... in general catch and shoot will be significantly better than off the dribble, but not always.
He has some warts for sure. I think his warts have some of the most believable excuses and also are areas that he can improve. I have him #4 and would love to trade up for him. I just don't see him being a bust... even if he does underwhelm.
His off the dribble and mid-range game is severely lacking. His best scoring ability is driving and finishing. Will he be respectable from open 3? I think so.
