Scenario: Oregon St defeats Oregon, Utah beast Colorado, Washington beats Washington St and UCLA beats Cal
Tied Teams: Oregon, Utah and Washington all finish 7-2, tied for the second spot
Tiebreaker 1 (H2H): Skipped because they haven’t all played one another
Tiebreaker 2 (Record against common opponents): They’re all 5-1 against common opponents (Wash St, Stanford, Colorado, Arizona, Oregon St, UCLA)
so it goes to the next tiebreaker
Tiebreaker 3 (Record against highest rated common opponent):
Both Oregon St and UCLA have 5 wins, all tied teams are 1-1 against 5-3 teams, then undefeated against lower rated common opponents. So next tiebreaker
Note that if UCLA were to lose to Cal, Oregon St would be the sole next highest-rated opponent so Oregon is eliminated. Starts over with a head-to-head tiebreaker between Washington and Utah.
Because Washington and Utah didn’t play, H2H tiebreaker doesn’t apply and it defaults to record against the next highest rated common opponent… which at this point would be Oregon, who Washington beat and Utah lost to. Washington gets the spot.
Tiebreaker 4 (Strength of Conference Schedule): (continuing on from the scenario where UCLA beats Cal)
The combined conference record of
Utah’s conference opponents would be 38-43
Oregon’s conference opponents would be 36-45 (or 37-44 depending on the Arizona/ASU outcome)
Washington’s conference opponents would be 32-49
