I have seen these on "X":
Scenario 1:
BYU Win
Utah Win (CO Loss)
Kansas State Win (ASU Loss)
Scenario 2:
BYU Win
Kansas State Win (ASU Loss)
Baylor Win (WVU Loss)
Cincinatti Win (ISU Loss)
I know scenario 2 is for sure. I am not positive about Scenario 1 because of ISU and WVU not having 3 losses. Anyone disagree? I know the tie breakers can be tough to sort out.
