My two cents: The Notre Dame-Stanford game got short-changed. Yes, the Pitt game may have had more on the line (for one team, at least) and had more twists and turns, but the Cardinal game had everything a football fan could hope for: The elements, the rivalry, the comeback, the back-up quarterback saving the day and, of course, the goal-line stand. ("College GameDay" being on-hand certainly turned the atmosphere up a notch, too.)
I'd throw that contest over the Michigan-South Carolina Outback Bowl, which featured the big Jadeveon Clowney hit and a back-and-forth final frame, but lacked the stakes that Notre Dame-Stanford and the other top-four games had.
Nothing, however, touches the SEC title game in my mind.
