I can’t really argue with the four teams that are in as they are the only P5 teams with 0 or 1 loss. I also agree with not having a Big Integer semi-final matchup. However, if conference championships are going to be played then they need to mean something.
In a similar argument that I have always used against the expansion of March Madness, which should have never expanded beyond 48 teams, practically every team is already in the tournament by virtue of their conference tournament. If you win your tournament then you advance. Taking more than 4 teams from a conference and placing them into a 68 team tournament is idiotic.
I feel similarly about college football in that if conferences are going to have a championship game then it should mean something. In a 12-team CFP it should mean an automatic bid (and probably will). But 12 teams is too many, a six team CFP is big enough. All P5 conference winners go along with the highest ranked non-P5 team. Losers of conference championships do not advance, regardless of record - Kansas State is in, TCU is out, Michigan is in. Ohio State, no, you lost. Clemson is in. Utah is in, UGA, and Tulane.
