He's a 4 time all star and on contract through next season so that gives the Jazz a year and a half of truly contending (assuming Hayward & Hill come back next year)
Utah receives Paul George.
Indiana receives Utah's 2017 1st rounder, Derrick Favors, Rodney Hood, and Dante Exum. Throw in OKC's 2018 1st rounder to sweeten the deal.
The Jazz would have a lineup of 1. George Hill 2. Paul George 3. Gordon Hayward 4. Joe Johnson 5. Rudy Gobert all with keeping Alec Burks, Joe Ingles, Trey Lyles, and Boris Diaw for depth.
I think they could seriously contend with that lineup.
