The Cotton Bowl isn't in Norman, and I'd argue it's a much harder environment to play in than Kansas' high school stadium. It was the biggest stage of the year for OU, and they stepped up and delivered in the clutch. I agree with you that if OU plays like they did against UCF, their chances of beating Kansas are low. However, I think it was a classic case of a team playing down to its opponent, and they'll be up for Kansas. OU is a proven team while Kansas hasn't proven that they can beat a quality team yet.
