His issue is if he is a pg/primary ball handler then the handle has to be very good because of a high center of gravity. If he is a wing the shot needs to be much better as he will spend more time off ball. In addition... he doesn't have a lot of burst. The defense doesn't seem good but he has tools to be a plus.
I loved him when the shot was falling because it opens up a lot of routes for him to contribute with that passing. He needs a lot of work. I'd take him with the Minny pick still but we will have to be more patient than we normally are with him.
Moving him to the wing also might make his shot look less bad. The FT% would suggest he would also suggest he's a bad spot up shooter though. The thing about watching him play live is that you might just get the impression he's a good shooter having a bad day. He takes high degree of difficulty shots with confidence and he's always been this way even on Real Madrid. Unfortunately, when you look down on the stat sheet's it's also always been apparent that he sucks badly at making these shots. Maybe if he's off the ball he can get easier shots and he won't be this terrible, but the more he's off the ball the less his special passing ability gets utilized.
To my eye, he's actually a pretty decent athlete and his handle is holding him back greatly...tough to tell if he has burst because he's either shielding the defender with his body or hanging on for dear life whenever he's actually trying to be on the offensive. If he went from D- level ball handler to a C+, he might look a lot faster....but sometimes it's hard to tell how much of it is lack of athleticism or skill that's holding it back. I don't think he's a Cody Williams where both the skill and the burst are an issue.
