Big 12 viewer's guide: Red River Showdown highlights Week 6

Preview: Oklahoma vs. Texas

Cary Chow and Edward Aschoff preview the Red River Rivalry where an upset minded Texas is looking to turn their season around.

Here’s a snapshot preview of Week 6 in the Big 12 (all times ET):

12 p.m.

No. 10 Oklahoma vs. Texas, ABC and ESPN Watch App: The Sooners are 17-point favorites, but since 1989, Texas is 5-2 when unranked and facing a ranked Oklahoma squad. That includes a 36-20 victory over the Sooners two years ago when OU was ranked No. 12. To have any chance of pulling off the upset, Texas will have to make QB Baker Mayfield uncomfortable. According to ESPN Stats & Information research, Mayfield is completing 62.5 percent of his passes thrown 20 yards or more, the best rate among Power 5 QBs with at least 10 such attempts. Texas redshirt freshman QB Jerrod Heard, meanwhile, has tailed off since breaking Vince Young's school record with 527 yards against California. His QBR in his past two starts is 20.0, including zero TDs rushing or throwing.

No. 3 Baylor at Kansas, FS1: The Bears are a whopping 45-point favorite over Kansas, which is the biggest spread among Big 12 opponents going back to at least 2004, per SportsInsights.com. Baylor has put up 255 points through four games, scoring at least 55 in each outing. According to the Elias Sports Bureau research, the Bears could become just the second team since World War II to score more than 300 points through its first five games; 2013 Baylor is the other team to achieve the feat. The Bears seem like a good bet to get there. Kansas is surrendering more than 40 points a game. Louisiana-Lafayette's 1997 team still holds the FBS season record with 50.3 points allowed per game. Given their remaining schedule, the Jayhawks could be a threat to break that record.

3:30 p.m.

Iowa State at Texas Tech, FSN: Texas Tech leads the all-time series versus Iowa State 10-3, including a 6-1 advantage in Lubbock. Tech’s average margin of victory in the past three games is less than a touchdown. Last week against Kansas, Mike Warren became the first Cyclone to rush for more than 100 yards in back-to-back games in his first season; Warren finished with 175 yards as Iowa State won its first Big 12 game since 2013. Tech ranks third nationally in scoring, trailing only Big 12 foes Baylor and TCU, whom the Red Raiders have faced in back-to-back weeks.

7 p.m.

No. 21 Oklahoma State at West Virginia, ESPN2 and ESPN Watch App: Both teams suffered season-ending injuries to key defensive leaders in the past week. The Cowboys lost linebacker and three-year starter Ryan Simmons to a torn MCL and PCL. West Virginia All-American hopeful safety Karl Joseph also injured his knee during a non-contact drill in practice earlier in the week. It will be especially interesting to see how the West Virginia secondary adjusts without Joseph. Oklahoma State QB Mason Rudolph has passed for at least 250 yards in each of his eight career games. According to ESPN Stats & Info research, that is tied for the longest active streak in the FBS. The last time the Cowboys lost to an unranked opponent when ranked themselves was at West Virginia two years ago.

7:30 p.m.

No. 2 TCU at Kansas State, FOX: Coming off a 50-7 rout of Texas, TCU has now scored 50 points or more in four straight games, which is a school record. The only Big 12 offense with a longer such streak was 2008 Oklahoma, which went on to set a modern FBS record for points in a season and played for the national championship. Manhattan hasn’t been kind to the Horned Frogs over the years, though. Kansas State has won three of four there, with TCU’s only win coming in 1985. TCU quarterback Trevone Boykin has now thrown a touchdown in 20 straight games, the longest active streak in the nation. That streak began against K-State two seasons ago.
