Having watched him at UK for his one season there, I thought he had a lot of potential. The most impressive things being, obviously his speed, but also his intelligence, attitude, and personality.
He didn't shoot well from the outside or even from the foul line as well as you would like for a point guard, but there was nothing about his shot that looked broken or in need of a major over haul. I felt like with a lot of work, lots and lots of repetitions, his shot would improve. Really felt like you would not see a lot of improvement there until he had a full off season to just work and work on that shot.
I was a little disappointed at first in his ability to manage a game early in the season, but he has started to show a lot of improvement there since sitting out a few games with an injury. I think he is trending on an upward path, but expect some bumps in the road.
He is a one-and-done rookie and there are a lot of adjustments to be made to play in the NBA. As he makes adjustments, opponents will make adjustments. NBA teams do an excellent job of scouting. It seems like a lot of people don't realize that. When a young player starts to get it and takes a step forward in his game, other teams take note and adjust to it. That is one reason for inconsistent play, it's a constant battle of adjustments. I cannot believe the number of fans that want to give up on a player as soon as he goes through a bad stretch.
If he can develop a consistent outside shot in the next couple of years, then he will be an all-star type player.
