Norman, Okla. ? Oklahoma defensive coordinator Mike Stoops scoffed when asked if his team spent any extra time earlier in the week looking at film of its next opponent, No. 5 Notre Dame.

“We worked on Kansas the whole week,” Stoops said following OU’s 52-7 victory over KU on Saturday. “That’s what I told our players. I said, ‘We work Kansas all week.’ Obviously, we think they’re a formidable opponent.”

The Jayhawks didn’t prove to be.

OU held a foe scoreless in the first half for the first time all season and also limited KU to just 3.6 yards per play.

“Overall, it was a pretty business-like four quarters for us. They didn’t come in and do a whole lot,” Stoops said. “We just played. It got a little boring, but we just played our base defense most of the night and just played ball.”

Later, Stoops hinted once again that he expected more surprises from the Jayhawks.

“We prepared for a lot more than what we saw,” Stoops said, “but that’s their decision.”

Part of the reason KU had OU’s full focus was its performance in a 20-14 home loss to Oklahoma State on Oct. 13.

“They outgained Oklahoma State a week ago. Again, I think that was good that they had an opportunity to win against Oklahoma State in the fourth quarter,” Stoops said. “That got our players’ attention.”

The Sooners have won eight straight games against the Jayhawks. Also, OU’s 38-point halftime lead was its largest since 2009.

Still, Stoops said there were areas where his defense could improve.

“I thought our tackling was very sketchy early,” Stoops said. “I thought they got position on us on one of the tight ends that dropped the ball down the middle — a route that we had worked and let him split our defense a little bit. Just little things like that.

“They picked our linebacker on a wheel route, and the quarterback didn’t see him. We had a guy running free. Some things we may have gotten away with that y’all may not have seen because you’re looking at so many different things, but just little things that we can get better at.”

With the victory, OU head coach Bob Stoops improved to 19-1 in October home games with the Sooners.

“Obviously,” he said, “I feel very good about the way our guys played here tonight.”
