I'd have to be convinced that his high turnover rate and complete lack of passing are the result of playing on a terrible team and not fundamental flaws in his game. Passing is utterly fundamental to our system, and he'll ride a lot of pine if he can't keep turnovers under control. And he doesn't seem like he has the ideal toughness we would want.
That said, he's smart, he has a lot of physical tools, and he came to basketball late, so he still has plenty of room to keep improving. I don't know if we'll have a draft pick in the 20s (where he's projected to go), but he definitely has potential.
