Because of the extra week and games conflicting with school years.
Plus the argument of “if you go to 5 then why not go to 8?”
Also, where does Notre Dame fit in, or any other (chuckle) Independent, haha, team?
Some of the “not their year” BCS bowls are played the same week as “their year” BCS bowls.
You need 7 BCS caliber bowl games.
Revolving (CFP, Sugar, Rose, Fiesta, Orange, Cotton and Peach) are already in place.
I’m with you, take the conference champions and the 3 best teams after that but again, the Irish.
Lastly it would mean 15 games for two teams, that’s a lot of football.
FYI, in this scenario you had
1 Clemson vs 8 Notre Dame
4 Oklahoma vs 5 Iowa
2 Alabama vs 7 Ohio State
3 Michigan St vs 6 Stanford
(out Florida St, UNC, TCU)
Iowa State @ 
Utah
