Winning, Storming, then Dropping in the Rankings

Michigan "won" against WMU as a 27.5 point favorite, and proceeded to storm the field.

Will this be the first time a team has won a game, stormed the field, and then dropped in the rankings, assuming Michigan drops? I haven't been able to find any other examples of this happening.

If this is the first time, this is some elite CFB trivia.
