Jae Crowder
Crowder is an esteemed Jazz alum, even though he only played in Utah for a season and a half. At this stage of his career, Crowder is not a rotation player anymore, but he can still be a good veteran influence.
Not to sound like a broken record, but Crowder has helped multiple winning teams over the course of his career. However, he is also a pretty impressive story as a late-bloomer. He came into the league in 2012 but didn't blossom until 2015.
Given how many young players are on the Jazz, Crowder's experience could help them reach their potential knowing his work ethic and expertise. Plus, what could go wrong with bringing back an old face even if he's not the player he once was.
