The winner of Bedlam Saturday night in Stillwater most likely will win the South and play Dec. 4 in the Big 12 championship game in Arlington, Texas.
Oklahoma State (6-1) leads the division. Oklahoma (5-2) and Texas A&M (5-2) are tied for second.
Here are possible scenarios:
If OSU wins
The Cowboys finish 7-1, a full game ahead of A&M even if the Aggies defeat Texas on Thanksgiving.
If OU & A&M win
The South ends in a three-way tie. OU probably wins the South. All three teams would own one win in head-to-head matchups. The division title would go to the highest ranked team in the BCS standings provided the winner finishes at least two spots ahead of the team it has lost to. In last week's BCS standings, OSU was ranked 10th, OU 14th and A&M 19th. With a win the Sooners would pass the Cowboys in the BCS standings and should finish at least two spots ahead of the Aggies.
If OU and Texas win
The Sooners win the South. OU and OSU would finish tied for the division (6-2). The Sooners would own the head-to-head tiebreaker.
