Temp's P4 proposal...
1. Four 20 team mega conferences in which teams are divided into four divisions of five teams each.
2. Each team plays its own division (4 games) and two games against each other division.
3. This eliminates the need for P4 teams to schedule one another out of conference so they can have 2 buy games to prepare. That adds up to 12 games.
4. At the end of the regular season, the division winners are matched up in conference semi-finals. The remaining division finishers can get one more game by playing the team in another division that finished in their same place (2vs2, 3vs3, 4vs4, 5vs5).
5. The two winners of those semi-final contests play in the conference championship game.
6. With an expanded playoff, the division winners are your 16 teams. The last two weeks determines seeding.
7. The others, and non-P4 teams can play in the meaningless bowl games.
