keeping a second B12 at-large team out. If a second B12 team does squeak in, many talking heads will be questioning it with the same narrative, as if they're some kind of BCS busters still.
Aside from the conference championship auto-bid, BYU's path to an at-large spot still pretty much requires them to be undefeated, other than perhaps a B12 championship loss to a higher-ranked team.
The polls are making it fairly obvious that a B12 team is going to get stiff-armed at 13 behind a 2-loss blue blood. Same old story.
