The defense is gutted (lose 3 DL, 1 LB, 3 CB and 2 S). The Offense only loses 4 starters, but it's 2 big ones (Huntley and Moss) that will be impossible to replace. The nice thing is that most of the OL is back (4 returning starters) so I'm hopeful the RBs behind Moss (who have combined for like 125 carries this year) will be able to run behind that OL, but Utah can't rely on field position and defense next year. They'll need to play some offense too, and I'm not sure that's likely.
7-5, maybe 8-4 if things break right. 6-6 if they don't.
