My other thought is that if FCS can do a 24-team playoff (after an 11-game regular season, no conference championship games), why can't FBS? If you start a playoff right after the regular season, the first set of 8 games would take the place of conference championship games and probably get better ratings on television.
We know that North Dakota State is probably going to be in the title game every year, but that doesn't diminish the excitement of the other 23 schools who are competing against them, with the outside chance of getting the upset of the decade or even the century in NDSU's case.
First Saturday of December (top 8 seeds get byes, reserved for Power 5 conference champions and 3 at-large):
- 9 seed vs. 24 seed
- 10 vs. 23
- 11 vs. 22
- 12 vs. 21
- 13 vs. 20
- 14 vs. 19
- 15 vs. 18
- 16 vs. 17
The second Saturday in December matches the winners of those games against the top 8 seeds, so eight more games with huge ratings and money, played at home stadiums.
That leaves quarterfinals for New Year's Day in the four traditional major bowls: Cotton, Sugar, Rose and Orange, with semifinals 7 to 13 days after that and a title game in late January. Those games can be played in Atlanta, Phoenix or another neutral site.
That doesn't eliminate a 12th game in a bowl for the teams that don't qualify. In fact, I'd say that the other 104 squads could all be invited to play a 12th game — an exhibition — somewhere warm or domed between Dec. 15-31 and between the second round of the playoffs and the New Year's Day quarterfinals.
