Other scenarios: The Big 12 also provided further details on potential scenarios involving the five teams who are currently 5-3 in Big 12 play and one game behind Arizona State, BYU, Colorado and Iowa State.
“For teams who are 5-3 entering the week, they must win and see at least three of the four 6-2 teams take a loss,” the Big 12 said, explaining that further updates would be available at Big12Sports.com as results become final over the weekend.
That means, if BYU loses, two or more of the other league-leading teams (Arizona State, Colorado or Iowa State) must also lose in order for the Cougars to stay in contention for the championship game, even with a loss.
