If they expand to 6 or 8 teams, I think the top Group of 5 teams say no to a potential game. Why risk the loss to BYU if they’ve got a legitimate shot to get in if they go undefeated?
However, if they keep it at just 4 or 5 teams, there would be more incentive for a team like UCF to play us in order to strengthen their resume as much as they can.
