Exum, Lyles, Burks or Hood, Neto, their 2017 first and our 2017 first. With Westbrook a free agent and likely to go to the Lakers, OKC has significantly lower leverage in trades. They won't get a better package from anyone except maybe Boston, since there's the chance Westbrook is a rental. Sell Westbrook on being part of the perfect team to beat Golden State and get his revenge on KD. As constructed, the only other teams he could join that would be more likely to beat KD with are San Antonio and Cleveland.
Westbrook
Hood
Hayward
Favors
Gobert
You swing for the fences for one year and go all in for a title, and still keep the core of the team intact if RW walks.
Really, I'd trade anyone but Hayward, Favors, and Gobert since I think adding Westbrook to those three makes the Jazz a contender.
