Sooners' offense humming after one quarter

Posted by ESPN.com's Tim Griffin

NORMAN, Okla. -- Any offensive hangover resulting from last week's loss against Texas appears to have been flushed away.

The Sooners put together their most balanced offensive outing of the season to streak to an early 14-7 lead over Kansas one play into the second quarter.

The biggest reason is the return of a sputtering OU running game that had produced less than 50 rushing yards in two of the Sooners' last three games. The Sooners are already at 69 yards rushing as they've dominated the line of scrimmage.

The Jayhawks have had big trouble covering Oklahoma's downfield passing. Quarterback Sam Bradford has taken advantage by torching Kansas for 189 yards by completing 16 of 22 passes.

But Kansas quarterback Todd Reesing has also been effective, taking advantage of a 40-yard kickoff return by Jocques Crawford to stake a 57-yard drive capped by Crawford's own 2-yard touchdown plunge.

The Sooners lost productive wide receiver Manny Johnson, who appeared to hyperextend his left elbow on the first drive. His return is questionable.

And Kansas nose tackle Caleb Blakesley limped off the field with an injury to his left leg midway through the first quarter.
