I was toying with this idea in another thread and I really think it's the future of FBS FB.

All conferences expand to 20 teams. A Power 4 and a Group of 4.

Expand the playoff to 10 teams with the 4 P4 champs getting an auto-bid along with the top 2 G4 champs and 2 wild cards. The top 2 teams get a bye in the first round and the first round is at the higher seeded teams home field then the semi's and finals are at neutral sites.

The regular season expands to 13 games and every conference plays 10 conference games.

No more games allowed against the FCS. The expanded conferences has enough teams where it's no longer needed.

Behold the expanded conferences! *Edited for teams I forgot to add*
