In football it's very common that you can point to a play that shifts the momentum of the game or perhaps wins/loses the game.
However, it's even more common in a sport like college football that you can point to a play or two that changes your season and that's what the Duke Blue Devils are starting at with a 5-7 record and no postseason to play in this season.
Duke started the season 4-2, with one loss coming in the first game of the season to then No. 2 Alabama. While challenging itself to play a National Championship contender, it's a game that perhaps kept the Blue Devils from playing in a bowl game as Duke could have played a non-Power 5 game or a 'cupcake' team as some would say.
