I don't think it makes much sense to look at other players or situations. I think it makes the most sense to look at his game. He has an NBA game offensively, but even in his current leagues he has a decent amount of TO's to go with those great assists. He's absolutely a good/great NBA level shooter,and has excellentt ball handling ability. He's also going to struggle defensively, and he's never played in such a rigorous, long season.
He looks like he doesn't take care off himself incredibly well, and as he gets older that could lead to injuries, or an earlier drop-off in his ability.
The Jazz also need to think about if bringing a guy like him over makes sense for their team depending on who else is on the roster. Is he a definite NBA starter on a top team? I don't think you can say that. I don't know if it makes sense for the Jazz to bring him in unless they consider Exum a bust/non PG, or they aren't planning on bringing back Hill. I guess if Hayward is on board I'd be fine rolling with him in a platoon with Exum for a year or two. But I'm higher on Exum than some people, who might want to move on immediately.
Edit: In that case he'd be an ideal backup. But he reportedly only wants to start.
Ehh, I havent heard anything about him saying he wants to start. I remember hearing he doesnt care about starting as long as he has a rotation role on the team.
