Only the four first round games are on campuses. Once the 4 opening games are played, they move to traditional bowl venues.
If we're basing it on the AP poll, ISU would be the B12 champ that gets a bye for the first round. BYU would not have a bye. We'd play a road game at the higher ranked at large team from the SEC or B1G. Then if we won that game, we'd go to a traditional bowl game site for the quarterfinals.
