Big 12 Week 3 primer

Today, Oklahoma and West Virginia will try out new quarterbacks, Kansas will attempt to end a streak, Iowa State will shoot for a rivalry win and Texas will look to stave off a catastrophe.

Those will be the major storylines for Week 3 in the Big 12:

Georgia State at West Virginia, noon ET (Root Sports): Dana Holgorsen made a surprise call this week by announcing Ford Childress as his starting quarterback. The Mountaineers had gone with Paul Millard the first two weeks, but when Holgorsen indicated Monday he would be making a change, the assumption was that it would be Clint Trickett. Instead, Holgorsen is banking the redshirt freshman Childress can spark a passing attack that’s been dormant so far this season.

Tulsa at No. 14 Oklahoma, noon ET (ABC): Like the Mountaineers, the Sooners will be starting a second quarterback. Trevor Knight was ineffective and injured his knee, opening the door for Blake Bell to get the start. The Sooners need to generate confidence in the passing game before heading to Notre Dame in two weeks. So if Bell struggles, Oklahoma won’t hesitate to give Kendal Thompson a shot. Thompson suffered a foot injury on the first day of the preseason, but returned to practice this week.

Iowa at Iowa State, 6 p.m. ET (FS1): The Cyclones have a golden chance to put the Northern Iowa loss out of sight and out of mind. A third consecutive win over its instate rival, and Iowa State will be back on track after a rough opener.

Massachusetts at Kansas State, 7 p.m. ET (K-StateHD.TV): Bill Snyder will continue to tinker to find the right blend of quarterbacks Jake Waters and Daniel Sams. Waters will get the start, but Sams figures to get more playing time. He’s jumpstarted the offense with his wheels every time he’s subbed in for Waters so far.

Kansas at Rice, 7:30 p.m. ET (CBSSN): The Jayhawks haven’t won a road game since Sept. 12, 2009. This is a winnable game for Kansas, which showed some offensive pop last week in its opener.

Lamar at No. 12 Oklahoma State, 7:30 p.m. ET (FSN): The Cowboys will attempt to take out their frustration stemming from this week’s controversial Sports Illustrated investigation into the program. Hapless Lamar figures to be the punching bag.

No. 25 Ole Miss at Texas, 8 p.m. ET (Longhorn Network): It’s been a long week for the Longhorns. Sunday, coordinator Manny Diaz was fired. Friday, they lost quarterback David Ash for this game. Can Texas win with Greg Robinson at defensive coordinator and Case McCoy quarterbacking the offense? They’ll have to, for Texas to avoid a nightmare 1-2 start to what was supposed to be a promising season.
