BYU stays undefeated but loses the CC game to Coach Prime.
Media would be happy to have Primetime in the playoff talk, no doubt, and they could stomach an otherwise undefeated BYU in there too I think, especially if SMU beats Miami.
But I can’t see any other scenario where B12 gets two. Maybe if ISU wins and ISU and BYU are both one loss teams? But that assumes the committee is playing fair.
