When you take away games against Group of 5 schools, here are the real conference records for each conference (not including the Cactus Bowl):
SEC 7-2
Pac Twelve 3-3 (includes victory against BYU)
ACC 3-3
Big Ten 4-5 (includes victory against Notre Dame)
Big XII 2-4
The Pac-12 went 3-0 against Group of 5 schools.
The ACC went 1-2 against Group of 5 schools.
The Big Ten went 1-0 against a Group of 5 school.
The SEC went 1-0 against a Group of 5 school.
The Big XII will not play a game against a Group of 5 school.
In other words, there's the SEC and then the other four Power conferences, separated by very little. The Cactus Bowl result won't change that.
