Absolute worst case scenario would be 4-8 with the best-case scenario probably being 11-1, but somewhere between 5-7 and 10-2 is more realistic. I know FPI predicts BYU at 7-5 on the nose, but looking at the game by game numbers I'd put the over/under at about 7.5 wins with 8-4 or better being a "success" and 7-5 or worse being a disappointment, though that's just solely on the FPI numbers.
