for BYU is to keep winning.
ND (if it doesn't lose again in the regular season) will likely play Clemson or Miami in the ACC title game. Expect at least 2 of those 3 to lose a game.
Indiana has to play OSU. OSU also plays Penn State.
Tennessee plays Georgia. LSU plays A&M and Bama. A&M also plays Texas.
Point is, there will be plenty of carnage still to come. The key is to get through it without a loss.
BYU keeps winning and they will be fine.
