The Big 12 title scenarios seem pretty straightforward. If OU, Baylor or Oklahoma State win out, they’re the champs. They all control their own destiny. Oklahoma State would be 12-0. So would Baylor. OU would be 11-1 would have beaten any other team that could feasibly be 11-1 and thus hold the tiebreaker (that was put in place after the TCU/Baylor debacle last season).
It gets messy when you look at a one-loss team not named OU winning the conference and three different teams being involved. Like, what if Baylor beats OU and OSU but loses to TCU.
