Oklahoma has a history of damaging opposing defenses both physically and mentally. This season, however, the Sooner offense has inflicted more damage than any in history.

In 12 games, OU has scored a school record 89 touchdowns and piled up 680 points. If the Sooners score13 points Saturday night against Missouri at the Big 12 championship game, which is pretty likely considering they’re averaging 53.3 points, they’ll pass Texas’ 2005 team for most points scored in 13 games. If they score 18, they’ll also own the mark for the most in a 14 game-season regardless of what happens in the bowl game.

By just about any measure, OU has set the standard for high-powered offense. There’s never really been anything like it.

“When you look at the point production and when you look at last week away from home, the whole second half we scored on seven straight drives,” OU coach Bob Stoops said Tuesday. “That’s against a really good team. To be honest, I haven’t seen that kind of efficiency, production and balance.”

Sam Bradford’s having the best season an OU quarterback has ever had, throwing for over 4,000 yards and 46 touchdowns. Five of the Sooners’ receivers are averaging more than 16 yards per catch.

There’s been some pass-heavy offenses that have put up similar numbers over the years. But those didn’t have two 1,000-yard rushers. DeMarco Murray has already passed the mark with 1,002. Chris Brown needs only 12 more to get there.

“I think it’s just 11 guys buying into the system that (offensive coordinator Kevin Wilson) put in front of us, and just buying into what he had to say,” Bradford said. “He has the best for all of us in mind, and it’s also just going out there and playing hard every week.”

The 61-41 victory over Oklahoma State marked the fifth straight game the Sooners scored more than 60 points and sixth straight to score at least 58. Those points came in what’s believed to be the toughest conference in college football.

But the offensive onslaught started long before six weeks ago. Last year’s offense was one of the most productive in school history. It set a school record with 80 touchdowns.

What’s been the difference?

Most point to the hurry-up, no-huddle offense installed this season. The style shift has given the Sooners more snaps this season. A year ago, OU averaged 69.6 plays per game. This season it’s averaging nine more.

But there has to be something else.

“You look at most of the guys on this offense and they’ve been in the system for three or four years,” wide receiver Manny Johnson said. “Most of us are guys that were already used to playing the college game. The speed of it really slowed down for us.”

Johnson’s right. OU cooked up the perfect blend of talent and experience this season.

There aren’t many teams that have this many veteran players playing on one unit. All of them, with the exception of wide receiver Ryan Broyles and fullback Matt Clapp, are finishing at least their second seasons as starters. The offensive line has basically been intact for the last three seasons. Some have been steady contributors since 2005.
