Big pickup for the Jazz. He's not the long, athletic shot blocker they still need inside, but he'll replace Boozer's scoring and rebounding. He's not as good a face-up shooter or as good in the pick-and-roll as Boozer, but he's a better back-to-the-basket scorer.
I know he had major knee surgery and inevitably struggled (at least by his standards) last season, but he's likely to bounce back next season and if he does, this is a steal. He's 25, a bonafide 20/10 guy when he's right and is signed for 3 years/$42 million. With the money being thrown around this summer, if he's fully back to where he was two seasons ago next season, that's a bargain.
Millsap is likely to be frustrated, though. It's one thing to back up Boozer, who was already on the team, but it's another thing to acquire his replacement. Probably feels like he's played the good soldier role long enough and is deserving of starting.
