The Big 12 Conference is opening its 25th season a week later than expected, and with just seven of its 10 teams playing. No. 15 Oklahoma State, TCU and Baylor all had their scheduled openers and only non-conference games postponed because of the coronavirus. No. 23 Iowa State opens against an FBS opponent for the first time in coach Matt Campbell’s five seasons. No. 14 Texas is a six-TD favorite over UTEP, while five-time defending Big 12 champion Oklahoma plays its first game with redshirt freshman Spencer Rattler starting at quarterback. He is the fourth different starter in four seasons for the fifth-ranked Sooners.
