Man, this was tough. I'll take input, to see if anyone thinks this would line up differently. And I don't mind retroactive changes.
You had Syracuse - Clemson - Oklahoma - Georgia going into the CCGs, with 1 loss Utah down at #10
Syracuse, Oklahoma, Georgia and Utah all won, Clemson didn't play in theirs. Would Clemson drop from #2 to #5, with Utah jumping all the way up to #4 based on their CCG win? Would they have been higher than #10 at 11-1? They had previously played one game against a ranked team (@Washington), and lost, before winning the rematch. Their best wins had been over 8-4 Washington State or 8-4 Arizona State, both at home.
I don't think a 1 loss Power 5 champion has ever been left out.
