Kansas/Houston. . . But if there is a 3 way tie 8-1 . . . KState/ISU are 8-0 against all other teams not in the tiebreaker, as KState lost to BYU and ISU lost to KState.
So if BYU loses to Kansas or Houston, we would lose the 3-way tiebreaker. Otherwise you move on to the next criteria, which combined record seems to favor KState at the moment.
Luckily after the champion is picked, the 2nd place team will lose in a H2H tiebreaker with BYU.
KState - Direct loss.
ISU - did not play each other, But highest rated common opponent is KState . . . which BYU won.
So if 8-1, and Texas Tech, Colo, Cinci all end up 7-2 or worse . . . BYU will likely be the Visiting team at the CCG.
Quick note, I am not 100% sure and could have this wrong. I just needed a quick break from work while I ate lunch
