Iowa State 37, No. 2 Oklahoma State 31 (2OT)
With a bye week over Thanksgiving, undefeated Oklahoma State needed to survive one gimme game before a make-or-break Bedlam on Dec. 3. Instead, the Cowboys' national title dreams broke early. In a classic trap game scenario -- ranked team playing an inferior opponent on the road on a weeknight -- Iowa State came back from a 24-7 deficit to take Oklahoma State to overtime. Brandon Weededn opened the second extra frame with an interception, and the Cyclones capitalized.
