I think Keyonte is a combo who can play on the ball. If you're drafting him that high it's because you think he can play on the ball with significant usage like a Markelle Fultz. One of Keyonte's issues is that he plays very fast, and he also tends to get sped up. He's rushing on some of his shot attempts and it's causing him to be off balance. His release is nice, but he's often drifting which is throwing his accuracy off. This also affects some of his turnovers. However, I think this can be fixed with coaching. Just in terms of physical talent, he's a higher level prospect than Hood-Schifino, imo. He's got good size if he's effectively your 1.
If the Jazz are drafting at 10, and the top 8 have gone about as expected, then the Jazz are probably deciding between George, Wallace and Black.
