No.
There's not 12 teams that legitimately have a claim to be national champs.
8 is enough. Nobody lower than ND can make a real claim IMO.
Still think it should be all FBS conference champs in the playoffs (10) and 2 at large. Give em a play in game.
It's definitely going to 8 sooner than later, so that's the Power 5 champs and 3 at large.
