So then why have Conference divisions or a Conference Championship if it means nothing? Michigan #4 in the country when they finished 3rd in their Conference division? SEC Champ in, ACC Champ in, PAC-12 Champ in...and then Ohio State because they pass the "looks" test? The Committee has to be hoping Wisconsin wins, or Clemson / Washington lose.
I don't really place any weight on those championships, so I can't give you an answer there. I think it should be the 4 best teams, and those teams could be left out based on championship stuff if say, for example, special teams has one game where they forget how to play football. Or, maybe one team loses a game that they win 9 times out of 10, oh and their starting quarterback happens to be hurt.
That's just my opinion.
