NORMAN, Okla. (AP) — Changes are afoot in the Big 12, even before Oklahoma and Texas depart for the Southeastern Conference. Fourth-ranked TCU has replaced the Sooners as the Big 12 team in the running for a College Football Playoff spot. The Horned Frogs already are in the conference title game heading into their regular-season finale against Iowa State. No. 15 Kansas State is a surprise contender for the other spot in the title game. The Wildcats would get in if No. 24 Texas loses to Baylor on Friday. If Texas wins, Kansas State would need to beat Kansas on Saturday night to qualify.
