The real championship is the conference championship. The national championship is kind of like the pre NHL Stanley Cup: we put most of our effort into winning our regional league, but season is over and these other leagues are out there so we might as well put something together and make some more money.
If Reading FC wins all their games next year they will be champions of League Two. When Tulane won all their games in 1998 they were champions of Conference USA.
If there were some way to have a flexible playoff system with anywhere from 2 to 8 teams participating, it would be optimal.
Basically, you would just expand or shrink the size of the playoffs until you have at least 1 SEC team in the field. I don’t think any reasonable person could find a problem with this.
There is simply no fair way to create a playoff, and thus no fair way to declare a national champion.
That’s the nature of a league with 65 or however many teams that play 12 games (let alone if you factor in G5 schools).
The system for crowning the champion is fucked alongside CFB being the most exciting season. The more you try to fix the former the more you take away from the latter.
80% of P5 teams have zero shot at a championship anyway and an expanded playoff only consolidates equity among loaded programs.
I can only speak for myself, but Oregon winning a game back in the day to get one win closer to making the Rose Bowl was as exciting, often more so, than Oregon winning a game to get one win closer to the playoffs. Starting next year the comparison won’t even be close.
