If Kansas State ends up winning the Big 12 Conference, but doesn't earn a spot in the national championship game, the Wildcats would be contractually tied to the Fiesta Bowl, which also has the first choice this year in choosing between the remaining automatic qualifiers and at-large candidates.
Might the Fiesta Bowl decide to pit Oklahoma against Kansas State, which beat it 24-19 on Sept. 22 in Norman?
It's unlikely, but not entirely out of the question.
The more plausible scenario involves Kansas State finishing ranked No. 1 or No. 2 in the final BCS standings, and OU getting a shot at avenging its other 2012 home loss.
A Fiesta Bowl representative told The Oklahoman last weekend that an Oklahoma-Notre Dame rematch would be possible if the Wildcats play in the national championship game.
Of course, a lot can happen between now and the end of the regular season. Depending on which schools become BCS qualifiers, and what agreements those schools or their conferences have with certain bowls, a two-loss OU squad could be left out of major bowls altogether.
The other possibility is that the Sooners simply lose another game; while a third regular-season loss wouldn't 100 percent dismantle OU's BCS chances, it definitely would diminish their likelihood.
