But notice every scenario where we win and Auburn wins, we win the West, unless Arkansas sweeps Ole Miss AND Alabama beats South Carolina.
We win + Auburn wins = MSU wins tiebreaker.
We win + Auburn wins + Alabama upsets South Carolina = MSU wins tiebreaker (MSU 4-2, Alabama 3-3, Auburn 2-4)
We win + Auburn wins + Alabama upsets South Carolina + Ole Miss wins two from Arkansas = MSU wins tiebreaker (MSU 6-3, Alabama 5-4, Auburn 4-5, Ole Miss 3-6)
We win + Auburn wins + South Carolina helps us finally + Arkansas wins two from Ole Miss = MSU wins tiebreaker (MSU 4-2, Arkansas 3-3, Auburn 2-4)
Basically, we need to win and Auburn needs to win. If those two things happen, the only way we do not win the West is if Alabama beats South Carolina AND Arkansas sweeps the DH from Ole Miss.
If we win, Auburn wins over UT and USC beats Bama, it doesn't matter what happens in Fayetteville.
