David Ubben South 1. Oklahoma State (5-1) 2. Texas A&M (4-2) 3. Oklahoma (4-2) 4. Baylor (4-3) 5. Texas Tech (3-5) 6. Texas (2-5) Texas A&M's winning streak has muddled the race somewhat, but all three of the top teams still have a chance to win. Here's how they can do it: Oklahoma State: As the only one-loss team, if Oklahoma State wins out, it'll win the South outright and advance to the Big 12 title game. The Cowboys could also clinch the division with a win Saturday and losses by Oklahoma and Texas A&M. Oklahoma: If Oklahoma wins out, it would likely advance to the title game, but the prospect of a three-way tie exists. If it's a two-way tie and Oklahoma beats Oklahoma State, the Sooners advance via head-to-head tiebreaker. Here are the Big 12 tiebreaker rules.* If it came down to the BCS rankings in a three-way tie, the winner would most likely be Oklahoma, who would be coming off a road win against a top 10 team in Oklahoma State. However, in a new rule change this year, if the top two teams are within a spot of each other in the BCS rankings, the head-to-head result is the tiebreaker. For example, if Oklahoma were ranked 10th in the BCS and Texas A&M was 11th, the Aggies would advance to the title game. Texas A&M: Texas A&M must win out, and hope Oklahoma beats Oklahoma State to force a three-way tiebreaker. The Aggies need Oklahoma State to lose to both Kansas and Oklahoma to advance via a head-to-head tiebreaker against Oklahoma. North 1. Nebraska (5-1) 2. Missouri (4-2) 3. Kansas State (3-4) 4. Iowa State (3-4) 5. Kansas (1-5) 6. Colorado (1-5) Nebraska is still the odds-on favorite in the division, and even with a loss at Texas A&M on Saturday, the Huskers would still be one home win*against Colorado away from winning the division. The Huskers could clinch the division this week with a win*against Texas A&M or a Missouri loss to Iowa State. Missouri's only chance to win the division is winning out and Nebraska losing to both Texas A&M and Colorado. Originally posted by ESPN.com - Big 12 Blog Click here to view the article.
