LUBBOCK, Texas – Disappointing. Bad. Flat out beaten.

These are some of the phrases OU players and coaches used to describe Saturday’s 41-13 dismantling by the Texas Tech Red Raiders at Jones AT&T Stadium, a place where the Sooners have lost their last three games.

“We didn’t play well on defense,” junior defensive tackle Gerald McCoy said. “I don’t know what was going on. We couldn’t get anything going; we couldn’t get any stops.”

What is most discouraging about Saturday’s defensive problems is that there have not been any signs of this defense cracking all season.

“When the defense has been playing so well throughout the whole year, it’s disappointing to come in here and have a performance like this. It’s always disappointing,” junior defensive end Jeremy Beal said.

Texas Tech was statistically the best offensive team the Sooners’ defense has lined up against this season, but this was easily the squad’s worst performance.

It gave up 549 total yards, 388 passing yards and 161 rushing yards – all of which are season highs.

“They moved the football on us,” head coach Bob Stoops said. “In the end, they balked us, ran the football, broke tackles, so you’ve got to give them the credit.”

Coming into Saturday’s game, the defense had allowed its opponents to convert on 32.3 percent of their third-down attempts, but the Red Raiders were able to make eight of 17 third downs.

“We never could get the stops when we had them on some third downs,” Stoops said. “We just couldn’t produce the stops that we needed when we needed them.”

The defense looked overpowered the entire game, and by the end of the third quarter, people wondered if it had given up.

“I think it’s the first time all season that our defense has looked that way,” Stoops said. “I don’t think it’s fair to say that they gave up. They weren’t as sharp as they have been all year.”

McCoy said he did not recognize the defense that took the field Saturday afternoon.

“As good as we’ve been playing on defense all year, and we allow something like that, that’s just no heart, no pride at the end of the game,” McCoy said. “That’s just not good enough; that’s not Oklahoma.”

The Sooners have to come home next weekend to take on Bedlam foe Oklahoma State Cowboys, an offense that averages 32.9 points per game – 34.7 points per road game – and 400.5 yards per game – 455.3 yards per road game.

But the Cowboys may be without senior quarterback Zac Robinson, who suffered a concussion on Nov. 14 against Texas Tech, because he has yet to be cleared to play by team doctors.

“We’ll regroup and you know Oklahoma State’s coming in next week, so go out with a bang,” sophomore linebacker Travis Lewis said. “What a way to go out than play your rival.”
