Kansas City, Mo. ? The best offense for Oklahoma was the Kansas University offense.

If the Sooners needed something good to happen, and they did against the Jayhawks, it was KU that provided turnovers and field position.

Oklahoma found an offense late in the game, continued to dominate Kansas with defense to the end, and finally wore down the Jayhawks in a 19-3 victory Saturday night at Arrowhead Stadium.

Kansas committed four turnovers and seldom threatened to score. It had just 97 yards total offense. The Jayhawks got just 11 yards and two first downs (one by penalty) in the second half.

KU averaged less than two yards per snap.

“The defense was just outstanding,” OU coach Bob Stoops said.

Oklahoma’s offense also struggled for a long stretch of this game. The Sooners had three turnovers and missed two field goals and an extra point.

“Give Oklahoma some credit, because they were in the same boat with us,” KU coach Mark Mangino said. “Their offense was struggling, too, but they found a way to get it done.”

Oklahoma got just 82 yards in the first half but finally took control with 224 yards in the second half. Most of that came in the fourth quarter.

“Our offense struggled in a big way in the first half,” said Stoops. “The second half we were able to open up and make some big plays in the passing game.”

The Jayhawks, known for their defense, finally collapsed in the fourth quarter. Weary from a game-long assault, Kansas could not hold off Oklahoma in the final 15 minutes.

“Everyone knows KU has been playing great defense,” Stoops said. “It was a credit to our guys that they had the toughness and discipline to get the win.”

It was not a thing of beauty, and the worries about the health of Adrian Peterson remain. Yet, the Sooners desperately needed a victory and will take it.

It gets Oklahoma back to 3-3 on the year with Baylor coming this week to Norman.

Kansas, despite its stumbling offense, very much was still in this game into the fourth quarter.

Down just 10-3, Kansas simply could not generate any kind of threat. The Jayhawks got just six first downs in the first three quarters.

The game actually was won in the first five minutes, when two interceptions were turned into a 10-0 lead.

Believe it or not, it was over. Kansas did nothing the rest of the way to make anyone think it had a chance to win.

“Our defense played great again, but we just left them out on the field too long,” Mangino said. “That was one of the worst offensive performances I’ve been around.

“When you have a chance to play Oklahoma that tough, and the defense is playing well, you have to get some offense.”

While OU is more than happy to take this victory, there are serious concerns about the rest of the season. The hottest topic is Peterson’s health. He played little in the game, and for the second straight week was not a factor.

He limped off the field in the first half after running for minus-4 yards on five carries.

As a result, the Sooners once again had trouble running the ball, and the passing game was erratic.

Oklahoma was much better in the second half but still struggled to generate points.

Finally, the KU defense cratered.

The Sooners found their offense just in time but questions remain. OU will need more offense, especially running the ball, for a strong finish.
