BYU really needs the P5 teams they have beaten to play well down the stretch. Specifically they need Arizona state or Utah to win the south and both to win most of their remaining games. They also need Baylor to continue to play well save perhaps the Oklahoma game and play for the big 12 title. They also need Virginia to win the coastal division. Finally they need Washington state to finish second in the north and USC to finish with a winning record even after BYU beats them
