Last year's final Massey ratings, which is a composite of all computer rankings.....
1. Ohio State
2. Notre Dame
3. Oregon
4. Georgia
5. Texas
6. Penn State
7. Alabama
8. Tennessee
9. Ole Miss
10. Indiana
11. Michigan
12. LSU
13. BYU
14. South Carolina
15. Missouri
16. ASU
17. Florida
18. Iowa State
19. Clemson
20. Texas A&M
So you'd have been looking at OSU, Georgia, BYU, Clemson, and Boise State as the auto qualifiers and then the next 11, so the bolded teams in the CFP plus Boise State.
7 SEC
5 Big 10
1 Big 12
1 ACC
1 MWC
1 Notre Dame
Not sure people would be real thrilled with that outcome. I think it'd almost be a statistical impossibility that 3 Big 12 teams make it, unless they massively beefed up their OOC schedules and won those games.
