Oklahoma football: Jay Norvell says Sooners need to execute

“We'll always continue to probe and find ways to attack an opponent, but it basically comes down to the execution, the ability to run the ball and attack the perimeter in the passing game,” said Norvell, Oklahoma's co-offensive coordinator.

The Sooners lost their Big 12 opener last weekend, 24-19 at home to Kansas State. The game swung largely on three turnovers — a Landry Jones fumble that was recovered in the end zone, Blake Bell's fumbled snap inside K-State's 5-yard line and Jones' fourth-quarter interception, which led to a Wildcats touchdown.

Through the first two games, junior Kenny Stills clearly established himself as Jones' go-to receiver. But against Kansas State, it was true freshman Sterling Shepard who stood out, grabbing seven catches for 108 yards and a touchdown.

Another true freshman, Trey Metoyer, was a five-star recruit and was expected to immediately contribute, but he's caught just 10 passes for 90 yards all season; he had 39 yards on three receptions Saturday.
