Oklahoma will need Texas to defeat Kansas State if they're going to win their eighth Big 12 title under Bob Stoops, but they'll need to care of business against TCU first.
The Sooners come into Fort Worth with a 9-2 record, and they're a solid 6.5-point road favorite, but the 7-4 Frogs are far from a walkover.
Under Gary Patterson, they're one of the few Big 12 teams who takes pride in their defense. Led by star DEs Stansly Maponga and Devonte Fields, TCU's defense is rated No. 35 in the country, giving up 23 points a game.
The Frogs will need their defense to keep them in the game, as Patterson clearly does not trust redshirt freshman QB Trevone Boykin, who was thrust into the starting line-up after Casey Pachall left the team in October. Boykin attempted only nine passes in their win over Texas on Thanksgiving.
Saturday's game will be the last for QB Landry Jones, a four-year starter whose put up dazzling career statistics but has never quite won over the Sooner faithful.
With TCU looking like a rising power in the Big 12, Saturday's game could be the start of a fierce rivalry.
