Taking stock of Week 5 in the Big 12:

Team of the week: Oklahoma. With their victory over Oklahoma State, the Mountaineers deserved strong consideration here. But by winning in South Bend, the Sooners delivered the Big 12 its best win of the year while vanquishing past demons. OU, which fell to 1-9 all-time against Notre Dame last season, controlled this game wire-to-wire in a 35-21 win. QB Blake Bell operated the Sooners' offense like a veteran in just his second career start. And the OU defense took it to QB Tommy Rees to force three first-half interceptions that allowed the Sooners to pad their lead. OU might have been one of the most overlooked teams during the preseason. After Saturday, the Sooners won’t be overlooked anymore.

Disappointment of the week: Oklahoma State. The Cowboys fell in Morgantown 31-21, despite being 18-point favorites. OSU sputtered all day offensively across the board. J.W. Walsh had a QBR of just 38.1 (scale of 0 to 100) and the Cowboys averaged just 2.8 yards per carry. The defense didn’t fare much better, allowing a West Virginia offense that had been completely inept to rack up 21 first downs. Dating to last year, the Cowboys have now lost three consecutive Big 12 games.

Big (offensive) men on campus: Sterling Shepard and Aaron Wimberly. Both the Oklahoma receiver and Iowa State running back sparked their offenses to big wins on the road. Shepard had five catches for 83 yards, and delivered the nail in the coffin to Notre Dame with a 54-yard touchdown reception to put OU back up by two scores in the fourth quarter.

In a 38-21 win at Tulsa, Wimberly produced Iowa State’s first 100-yard rushing game in more than a year with 137 yards on 19 carries. He added a 31-yard reception as the Cyclones came alive in their first win of the season.

Big (defensive) men on campus: The Oklahoma linebackers, and Sam Carter. Corey Nelson, Frank Shannon and Eric Striker came up with huge plays in the first quarter to set the tone for the OU defense the rest of the way against the Irish. On Notre Dame’s first series, Striker blindsided Rees from behind, popping the ball loose into the arms of Nelson, who returned it 24 yards for a TD. On Notre Dame's next play from scrimmage, Shannon caught a tipped pass and returned the interception 17 yards to the Notre Dame 32. The Sooners scored again four plays later on an 11-yard run by Damien Williams. OU rode the defensive flurry all the way to the win.

Carter, TCU’s junior safety, had a huge day against SMU. Carter had two interceptions, forced a fumble and recorded a sack in the Horned Frogs’ 48-17 victory over the Mustangs. For his efforts, Carter was named the Walter Camp national defensive player of the week. With cornerback Jason Verrett ailing with a shoulder injury, Carter might have to take an even bigger leadership role in the TCU secondary moving forward.

Special-teams player of the week: Jaden Oberkrom. In a complete downpour, TCU’s place-kicker nailed two field goals to help the Horned Frogs pull away from SMU in the second half. As the rain began to fall in droves early in the third quarter, TCU had the ball on the SMU 5-yard line trailing 10-7. Because of the rain, a botched shotgun snap resulted in a loss of 20. But Oberkrom made sure the Frogs came away with points with the 35-yard field goal conversion. Had Oberkrom missed, who knows how the game would have gone for TCU? Instead, buoyed in part by getting points off the drive, the Frogs dominated the rest of the way.

Play of the week: After Josh Stewart took a screen pass 73 yards for the touchdown and Justin Gilbert intercepted Clint Trickett three plays later at midfield, the Cowboys seemed to be on the verge of blowing the game away in the first quarter. Instead, West Virginia cornerback Ishmael Banks read Walsh’s eyes off a rollout, stepped in front of the pass for the pick, then returned it 58 yards for a touchdown. The Cowboys never found their footing again offensively, as West Virginia held them to just two scores the rest of the game.

Stat of the week: Oklahoma State running back Jeremy Smith rushed for just 1 yard on 15 carries at West Virginia. According to ESPN Stats & Info, Smith’s rushing total was the second worst by an FBS running back with that many carries in any game in the past 10 years.
