A weekend of watching Oklahoma and Texas Tech will tell the Longhorns where they stand in the Big 12 and the BCS – and whether a team that spent a month at No. 1 will still have a chance to play for a national championship.

The Longhorns (11-1) wrapped up their last piece of business for the regular season with a 49-9 win over rival Texas A&M on Thanksgiving night, snapping a two-game losing streak to the Aggies.

Now it's up to the complicated BCS standings and Big 12 tiebreaking system to see where and when Texas plays next.

If Oklahoma beats Oklahoma State and Texas Tech beats Baylor on Saturday, the Longhorns, Sooners and Red Raiders will finish in a three-way tie for first in the Big 12 South. The league tiebreaker will send the team rated highest in the BCS standings to the Big 12 title game next week against North division champ Missouri.

Right now, that's Texas, which holds a razor-thin margin over Oklahoma at No. 2. But it is widely expected that a Sooners win would bump them past Texas in the BCS.

If the Sooners lose and Texas Tech wins, the Red Raiders hold the head-to-head tiebreaker with the Longhorns and would represent the South division in the Big 12 title game. If Oklahoma wins and the Red Raiders lose, then Texas gets in based on its win over the Sooners.

The Longhorns are hoping they can somehow manage to hang on to that No. 2 spot after handing A&M the worst beating in the bitter rivalry since 1898.

“I think we played a heck of a season, beating Oklahoma, beating Missouri, beating Oklahoma State, all those teams, and to come out here against our rival Texas A&M and winning,” senior defensive tackle Roy Miller said. “We can't control what's going on ... but a lot of things can happen.”

Coach Mack Brown said he believes his team deserves a shot at the BCS title, but was a bit guarded in his postgame remarks.

“I think voters have a tough decision because there's a lot of really good football teams out there. Oklahoma is a great team. Texas Tech is a great team. I do not want to sit up and take anything from any one of those teams,” Brown said.

“I do think that if we go to the Big 12 championship, it will probably be because we are a great football team and we did beat Oklahoma on a neutral site. We lost on the last play of the game out at Tech,” Brown said. “I'm proud of our guys ... This team has been unbelievable this year.”

Brown was more emphatic about quarterback Colt McCoy and his chances of winning the Heisman Trophy after another big game. McCoy passed for 311 yards and two touchdowns and ran for two more scores against the Aggies.

“I do think he's the most valuable player on one of the best teams in the country. What a great night and what a statement for him for awards here at the end of the year,” Brown said.

McCoy got career win No. 31, passing Vince Young to set a school record for starting quarterbacks while still just a junior. He also set a Texas season record with 3,594 yards passing.

Brown and his staff counsel their top junior players to consult with the NFL on their potential draft status. McCoy said last week he'll do that, but has maintained he plans to play for the Longhorns as a senior. He has not been projected as a first-round draft pick.

In Brown's 11 seasons at Texas, only three players – Young, running back Jamaal Charles and tight end Jermichael Finley – have left early. Only Young was a first-round pick, drafted No. 3 by the Tennessee Titans in 2006.

Thursday night's victory was special for McCoy because it was his first in three tries against the Aggies.

“It's been a great season and we finished strong and left it all out on the field,” McCoy said. “I thank God for giving me this opportunity to play for this team.”
