we would be out since we would not have all played each other (so no head-head). Both ISU and KSU would have lost to better teams than us (KSU to BYU and ISU to KSU, whereas we would have lost to to one of the remaining teams on our schedule). There might be other 1-loss teams but it wouldn't matter as KSU would still have a better loss than us. This is according to rule "b" under "Multiple Team Ties".

The only sure way to get in is to remain undefeated. Even if ISU loses to a lower ranked opponent, KSU would have the better quality loss (to us ironically). If ISU has two losses and we have one and KSU wins out, we get in based on head-to-head against KSU, unless there are other 1-loss teams. Then it gets too complicated to figure out.
