If I'm reading the rules correctly, no one except Oklahoma controls their own destiny, and no one except A&M has been eliminated.
If Oklahoma wins, they're in the championship game.
Texas needs to win and have A&M win (fat chance, D00MT).
Missouri needs to win and have Texas win.
Everyone in the other bracket has a 1-1 record, so...
Nebraska needs a win and a Baylor loss.
Baylor needs a win and an Okie State loss.
Okie State needs a win and a Kansas State loss.
Kansas State needs a win and a Nebraska loss.
