Three one-loss teams in the Big 12 South have put together strong arguments for a spot in the BCS national championship game. To remain in the running, Texas will need to avoid a third straight upset loss to rival Texas A&M.

Currently second in the BCS standings, the fourth-ranked Longhorns look to help their chances for a trip to the BCS title game for the second time in four years when they host the struggling Aggies on Thursday night.

Texas (10-1, 6-1) is one of three teams atop the Big 12 South with identical overall and conference records. Like Texas, Oklahoma and Texas Tech have spent time as favorites to make the national championship game, but the three teams have beaten up on each other in conference play.

The Longhorns knocked the Sooners out of the top spot in the AP poll Oct. 11 before dropping out of first place with a loss to the Red Raiders three weeks later. Texas Tech was No. 2 in the AP poll before falling to Oklahoma on Saturday.

That complicated in the BCS standings. The Longhorns currently have the coveted No. 2 spot, which would pit them against No. 1 Alabama if the season ended today.

But Oklahoma - currently No. 3 in the BCS - has a great opportunity to overtake Texas with an impressive showing against No. 11 Oklahoma State on Saturday.

"You've got to give the BCS credit," said Texas coach Mack Brown, who's long supported a playoff in favor of the current system. "They've got more talk about college football than ever before."
