No. 20 Oklahoma at Kansas State (11 a.m. Saturday, Fox Sports 1): Oklahoma coach Bob Stoops is tied with Barry Switzer for most wins in program history at 157 and will be alone as the coaching wins leader for the Sooners (8-2, 5-2 Big 12) with a win Saturday. But the Sooners will have to top Kansas State (6-4, 4-3) and coach Bill Snyder on the road. Snyder was on the coaching staff at Iowa when Stoops played there from 1979-82. Stoops also served as an assistant on Snyder’s staff at Kansas State. So these coaches know each other, and both teams need a win to bolster their records and perception. This one should be a battle.Kansas at Iowa State (7 p.m. Saturday, Fox Sports 1): The streak is dead. Kansas, which had lost 27 straight conference games, topped West Virginia last weekend for its first Big 12 win since beating Colorado in 2010. Kansas coach Charlie Weiss got a Gatorade shower, and the Jayhawks fans tore down the goal posts. But now it’s time for Kansas (3-7, 1-6 Big 12) to try for a different streak, a winning one. While the Jayhawks are on the road, what better team to play than Iowa State (1-9, 0-7), a team that hasn’t won a conference game since last season … when it defeated Kansas. No. 4 Baylor at No. 10 Oklahoma State (7 p.m. Saturday, WFAA/8): Baylor (9-0, 6-0 Big 12) can make its BCS statement in Stillwater, Okla., against the Cowboys (9-1, 6-1 Big 12), one of the preseason favorites to win the conference. The Bears, whose offense leads the nation in scoring, yards per game and several other statistics, have won a program-record 13 straight games and are trying to complete the greatest season in their program’s history. But Oklahoma State presents a tough road challenge. The Cowboys have bounced back from a loss at West Virginia to open Big 12 play and have won six straight to set up a huge matchup with Baylor.
