play each other in the regular season.

B12: BYU-Colorado-Iowa State
ACC: SMU-Miami-Clemson
B1G: Oregon-Penn State-Indiana

And, even the SEC has 3 of its top 5 contenders that don't play each other: Texas-Tennessee-Ole Miss

Indiana and Penn State (or Oregon) will be able to show off nice-and-shiny win-loss records to remain the CFP field because they don't have to play each other or Oregon or in the CCG. My feeling is that either Indiana or Penn State would finish no better than 9-3 this year if they had to play the top teams.
