I wouldn't be surprised if many on the team transfer. They also lose a lot of their biggest players to graduation/eligibility running out. And BYU, while losing a lot, might just be able to reload with Ratzliff set to return.
Probably be a lot harder for them to come into Provo next year and get a win, much less win the conference. They were so hyped this year because of all the veteran experience they returned.
Next year will be quite a rebuild. If there's any glimmer of hope for them, it's that BYU is doing what they've done so far this year after finishing last year with 5 losses in a row, largely due to terrible and inexperienced QB play. And yet, now at where BYU is. Maybe he's thinking they could have a similar turn of good fortune follow the same pattern as BYU in their 2nd year in the conference, but I just don't see that happening.
