What a week in the Big 12 football conference! Utah stayed perfect by routing Cincinnati 49-25, Texas Tech came back to beat Arizona 34-26 behind Tommy Castellanos, BYU held off ASU 27-20 on a touchdown the Big 12 later admitted shouldn’t have counted, Iowa State stunned Oklahoma State 51-49 on a walk-off field goal, and Colorado finally got its first Big 12 win in overtime against K-State.
