Cincy will have a top-6 road win, the CCG victory over 11-win Houston, 30+ point wins over 8-4 UCF and 8-4 SMU and zero losses.
OSU will have three top-15 wins, but nothing that can compare to Cincy's win over Notre Dame...and, they lost to 7-5 Iowa State and struggled against 7-5 Boise State (1-point win).
It would be full on conspiracy to place Oklahoma State in the CFP ahead of undefeated Cincinnati.
