If they had 7 games, there will be Liberty, Idaho States, UMass, NMSUs.... and
many CBers really seem to complain about that competition (UConn, UNLV...). Those are the teams willing to play during late October and November (because of their independence schedule and G5 affiliation). Plus, BYU would need to start scheduling 1 and dones with FBS or 2-1 with lower G5s.
