I think that their best hope would be to add an All Star caliber player and have them take a jump up in their development. Get somebody like DeMar DeRozan, who would be the #1 guy in Utah, and then have him do what he does (and what got him to the All Star game twice) as well as start shooting 3's at a high clip. All of a sudden, they have a legitimate franchise guy and the rest of the Jazz look pretty damn good with a guy like that.
I guess, the idea is that if you took the core of Gobert, Favors, Lyles, Hayward, Hood and Exum and then added a star to that group. . . that would be a pretty damn good team (as long as Burke, Withey and Johnson never have to see the court.) With a little luck, that would be a contending team. I like a team that can play defense at the end of the season much better than one that can score, but can't stop people.
