2 at-large would be better, with an 8-team playoff
I agree.
I would even rather go to 12, with 10 auto-bids. Just to have a reason to care about mid-major conference races. Then those 4 other Go5 champs get slaughtered in a true road game that first week. And if once every few years a 9-12 beats the worst P5 champ, or a Big XII runner-up, before losing in the quarterfinals anyway, does that really matter?
I do think to get to this the current conference structure needs to be drastically changed. You can't have a team sneak into a CCG after an 8-4 (5-3) type season, based on tiebreakers to win a 3 way tie, and then pull one upset.
That will never happen, but what if you got rid of divisions, then saved the final week for 1 vs. 2, 3 vs. 4, etc... Don't even call it a conference championship. Just call it the final regular season game. If the #1 team is somehow 2 games clear of the field, cool for them. But it will generally be a de facto championship game. Granted if those teams already played, and the reverse team won the second time, then you clear H2H tiebreaker, and that could lead to it not being a conference championship.
But either way, if you are going to guarantee that the top two teams play, I'm ok letting that winner in no matter what.
