Any reasonably experienced vet min PG picked up from the trash heap can get a team into a set and get out of the way. But the Jazz obviously isn't expecting Keyonte to become a Tyus Jones like ball-mover. He's getting minutes because they want him to function on a higher level eventually.
The biggest problem on offense is that he seems to be a really bad shooter, and having the defense respect him at the arc is the only way for him to gain an advantage since he's not very quick for a 6'3'' guard. If he can't magically become a 36% shooter from the perimeter, that may change his whole career trajectory.
I've said many times that Keyonte has an eye for cutters and a good sense for how players are moving around the floor. Unfortunately, he can't just stand in place and keep whipping the ball at guys diving to the hoop.
I'm ready to accept that his offense has time to develop, hopefully after he does a TON of work next offseason. But he has no excuses for his defense. Key simply doesn't compete hard enough and often looks like an entitled high school star with the way he gives up on plays.
IMO it wouldn't hurt him to spend some time in the G-League. We don't need him at the moment.
