I am looking at conference standings more than strength of record. Whatever keeps BYU in the front of the conference race is what I want. With that in mind:

Big12 Matchups:

ASU vs Cincinnati: It's a wash, they are in 5th and 6th place. Just enjoy watching it and seeing how AZ State's new QB looks.

Houston vs Kansas: It's a wash, they are in 11th 16th place. I don't even know if this would be enjoyable to watch.

Colorado vs Arizona: Root for Arizona so Colorado drops in the standings. And it makes BYU's win over Arizona look better.

Baylor vs Texas Tech: Root for Baylor so Texas Tech drops in the standings. And it makes BYU's win over Baylor look better.

UCF vs Iowa State: Root for UCF so Iowa State drops in the standings. And it makes BYU's record, since they play UCF, look better.

K State vs West Virginia: I'm torn. I want K State to keep winning because BYU's win over them looks good, but if West Virginia wins then K State drops in the standings. I think I'm rooting for West Virginia.

TCU vs Utah: TCU for so many reasons.
