1. Move to 14 teams just like the NFL.
2. Only the Big 10 and SEC Champions get a bye.
3. ACC and Big 12 Champion gets an auto host but not the auto 3/4 seed.
4. SEC and Big 10 split the other 4 host spots, 2 and 2.
5. 5 guaranteed spots for Big 10 and SEC, 1 guaranteed spot for ACC and Big 12, 2 at large for P5 or G5 (if we must).
6. 5 guaranteed spots from SEC and Big 10 are based solely on SEC standings (conference W/L records). 6th team from each conference could be at large.
7. Make a G5 8 team playoff. Top G5 team can play up into P4 playoffs as an at large (again if we must) or can opt out and play in the G5 tournament where they would actually have a chance to win a National Championship.
I would love for somebody to poke holes in all this but this seems to appease all parties involved.
