ranked (conference standings) common opponent. That would be KSU, so we'd hold the tiebreaker over ISU even if we lose to a team not named ASU.
The third tiebreaker would be win percentage against ALL common opponents....thats where we could run into trouble, but we'd already win based on tiebreaker rule #2: record against the highest ranked common opponent.
Side note: the 1st tiebreaker rule is H2H as I noted, but that is only valid if all teams played each other....we didnt play ISU so we can't use that tiebreaker rule.
