There's almost a 0% chance the Jazz can make the roster better (on paper at least) by not running it back. You have to get Conley back, and once that happens the avenues to change the team are pretty limited.Running it back idea is just simply making it easier for Donovan to decide on leaving the Jazz much sooner imho. It won't work and we'll have another Dame situation in Utah as well. If the new owner is all in making big changes then do it!
The best case scenario is that Jazz run it back and make tweaks to the roster so that Quin feels more comfortable developing the 10th-11th man on the roster.
