Coming out of last spring, Oklahoma was expected to march to its seventh consecutive Big 12 title and potentially challenge for the national championship with the best team in Lincoln Riley's tenure.
A lot has changed in a year. The Sooners were dethroned by Baylor, Riley is now at Southern California and the race for this year's conference title is completely up in the air.
Oklahoma is hoping to rebound with former assistant Brent Venables now in charge of the program. Texas is looking to improve after Steve Sarkisian's first season ended with a losing record. Oklahoma State wants to go one step further after narrowly losing in the league's championship game but lost several important pieces.
