Oklahoma has played all season like a magical aura surrounds them at Owen Field. No matter how they've looked the week before or how many injuries they've suffered, the Sooners play like they're invincible when they play at this field.

They certainly looked that way in Saturday's 27-0 Bedlam romp over No. 11 Oklahoma State.

"We had fans behind us and it gives us a little adrenaline," OU wide receiver Ryan Broyles said.

Or a bunch depending on how you want to look at the Sooners this season.

The victory, which was OU's 30th straight at home, lifted it to 7-5 and 5-3 in the Big 12. All but one of those conference victories came on its home turf. But it's hard to argue, Saturday's performance stood out above all the rest.

There's no masking the Sooners' historic dominance, winning 81 of the 104 meetings and the last seven over their in-state rival. But Saturday's game has huge implications for the Cowboys. A victory likely would have set them up for an at-large berth in a BCS bowl game.

Those hopes ended after they crashed into the wall they didn't see coming in Norman.

The Sooner defense, which was trying to make amends for last week's 41-13 loss at Texas Tech, was dominant to say the least.

The Cowboys, who entered the game averaging over 32 points a game, never threatened to score. They only gained 109 total yards and averaged a minuscule 2.1 yards per play.

"We had a lot to prove today, especially for the seniors," OU defensive end Jeremy Beal said. "We've had a difficult year and we just wanted to come out on top with a great win."

OU thought it would have to win with defense Saturday. That was no secret, but even OU coach Bob Stoops admitted his faith in what his offense could do was hanging by a thread when the day began.

Left tackle Trent Williams suffered a concussion Tuesday. The hope was he would be healthy enough to play Saturday. Those thoughts ended about 90 minutes before kickoff.

Williams' absence marked the 10th different Sooner starter to miss a game due to injury this season and eighth on the offensive line.

"I gotta admit, I was doing my darnedest to stay positive. But it was tough. I can't lie about it," OU coach Bob Stoops said.

The Sooners didn't play like a team that had deficiencies. OU plugged tight end Eric Mensik in at tackle and played one of it's best games of the season.
