Jazz don't have a max slot available UNLESS they renounce the rights to Kanter and Booker. It's not about the LT, the Jazz have to fit an offer under the cap. With the emergence of Gobert, I can see the Jazz trading Booker (Favors and Kanter get more time at PF). But I just don't see them giving up on a 22 yr old who is showing real improvement. Not with his size and offensive talent. Jazz need 3 man rotations at the bigs and wings and 2 PG's (or 3 guards and 2 SF's if they have a a combo guard). Gobert, Favors and Kanter are a potentially dominant trio of bigs. Hayward, Burks and Exum give Utah 3 of their 5 at the 1/2/3 spots. Hood might be a 4th. There are several directions Utah can go (SF, SG or a combo guard).
In terms of a FA, I think their best shot might be Demarre Carroll. Either convince him to be a 6th man or promise him a starting position, move Hayward to SG and bring Burks off the bench. Then upgrade at PG by replacing Trey with a "3 and D" player. Perhaps a starter for 1 season who then becomes Dante's backup.
C- Gobert/Kanter
PF - Favors/Kanter/Draft pick
SF - Carroll/Hayward
SG - Hayward/Burks/Hood
PG - Vet (trade or FA)/Exum/Neto or draft pick
