Added school icons and E/W boundaries, but 14 teams, would mean BYU could do the following (without playing a G5 at all-which I prefer).
1. Play your division (6 games), play east division (7 games). Yes that is 13 games and a tough go, so how about option 2.
2. Play your division, (6 games), play east division (5 games) for 11 then play another P5 team (low or mid tier) school (Say ACC, at home). Following the next year, play those east division teams that were dropped previous year and cycle through one other P5 team (low or mid tier) from the other P5 conferences (Say ACC, away, then Pac12 at home, following same pattern down the rest of the P5 conferences). Okay, maybe not, too difficult you still say, how about option 3.
3. Play your division, (6 games), play east division (5 games) for 11 (Following the next year, play those east division teams that were dropped previous year), then play 1 G5 school (and they travel to your stadium, no question).
What option would you prefer to do, annually? Option 1, 2 or 3?
