SC is locked into 6th, Cal and Utah both have the tiebreaker over them. If Utah beats Stanford and Cal loses to CU, Utah is 4th, Cal is 5th. If either Utah loses to Stanford or Cal beat CU Cal is 4th, Utah 5th.
Edit: If Colorado beats Cal it doesn’t matter what Utah does vs Stanford, Utah will be the 4th seed due to having the tiebreaker over Cal.
