This game has huge postseason implications for both teams. TCU and Oklahoma State have aspirations of reaching the Big 12 title game and beyond, and any loss would hurt those chances. TCU has more to lose, given the Frogs' brutal road schedule. They already survived an early test against Arkansas, but now is when the games really start to matter.
