You're gonna give the Sun Belt and CUSA and MAC an auto-bid, and leave out a top 10 team?

Your 2015 playoff looks like this

edit: I ordered the ranking stupidly, they wouldn't put the at-larges at the end

1. Clemson 13-0 (ACC)
2. Alabama 12-1 (SEC)
3. Michigan State 11-1 (B1G)
4. Oklahoma 11-1 (Big 12)
5. Iowa 12-1 (at large, next ranked in playoff rankings)
6. Stanford 11-2 (Pac 12)
7. Ohio State 11-1 (at large, next ranked in playoff rankings)
8. Houston 12-1 (AAC)
9. Western Kentucky 11-2 (CUSA)
10. Bowling Green 10-3 (MAC)
11. San Diego State 10-3 (MWC)
12. Arkansas State 9-3 (Sun Belt)

With a 12 team (4 team bye) bracket, the initial matchups are 5v12, 6v11, 7v10, 8v9

Houston - Western Kentucky (Winner plays Clemson)

Ohio State - Bowling Green (Winner plays Alabama)

Stanford - San Diego State (Winner plays Michigan State)

Iowa - Arkansas State (Winner plays Oklahoma)

That would probably be 4 blow-outs, at that point, leave it at 8 in the playoff, the bad G5 teams don't deserve a shot
