Week 13 of the college football season continued to show that the Big 12 remains as compelling as any other conference in college football. And as a result, the Big 12's chances of having multiple bids to the 12-team College Football Playoff are in serious jeopardy after both of the conference's two top-ranked teams were upset on Saturday.

The loss by the Crimson Tide at Oklahoma also raised some serious questions about the Kalen DeBoer and the challenges of following a coaching great like Nick Saban. Clemson, meanwhile, got a boost in their hopes by slotting ahead of those two SEC schools.
