I looked over the bios of the committee here:

Their backgrounds suggest they won’t be overly B1G or SEC centric but may lean to some East of the Mississippi bias. Several members have XII connections. I think there may be some ACC bias based on backgrounds.
BYU’s wins vs KSU and SMU give us a very good resume to date. I suspect that will wane over time as the chance those teams lose increases or the resumes of teams BYU is competing in ranking with improve as they get better wins. I do fear the ACC will be favored over the XII for getting a second team in down the stretch. I still think BYU is in for sure if their one loss is in the CCG in a close loss to the winner. If BYU is instead 11-1 and misses the CCG or 11-2 with a CCG loss, I don’t like our chances for a CFP appearance.
