something that could look like BYU playing a schedule like this:

Week 1 - @Utah
Week 2 - Utah State
Week 3 - Power 5
Week 4 - FCS
Week 5 - @Temple
Week 6 - UCF
Week 7 - @Houston
Week 8 - @Tulsa
Week 9 - Boise State
Week 10 - Cincinnati
Week 11 - @ West team
Week 12 - Memphis

With two divisions, BYU would cross the Mississippi River once maybe twice a season, something they are already doing in Independence.
