I like Bolomboy a lot. The Jazz just need to be patient. He's very raw, but has some tools for coach Q to work with. He should spend time in the DLeague this year and maybe next.
As for the hill vs Teague debate. I don't think anyone is saying hill is better, though I'm not sure Teague is better either. But, Hill better fits the makeup of our team. Both Hayward and hood need the ball and generally set up and run the offense. Hill is better playing off the ball and is very good defensively. Also, hill has more versatility, being able to switch from the 1 or 2, and is a better shooter and Hill allows for Exum to get more time. Think he will be much improved. If Exum surprises this year, it's a much smoother transition to move Hill to the bench. I'm not sure Teague would except that kind of role change.
I don't see what people see in Teague that makes him so special. Dude over achieved a couple years ago, but showed who he truly was last year. He's average. Dime a dozen. Decent pg skills with limited defense. Hill brings more to the table, above average shooter and defender, can start or come off the bench, play off the ball, and multiple positions.
Teague might be the better player on Indiana, but Hill is probably the better player on the Jazz.
