If they want to fix it, they have to go with conference champions and get to a P4 where the CCG is in reality the first round of the playoffs. Personally I would like to see a P4 with 80 teams and have CCG semi-finals with PODs in each P4. That would put 16 teams in the playoff running with not as much duplication of games and no games where two teams from the same conference would be in the CFP.
I think the G5 should go their own way with their own 4-team playoff. They aren't ever going to be included so why fight something you can't win
