Edwards had claimed the top spot in the Chase for the Sprint Cup championship a week earlier and was locked into a tense title race.
Bowyer used the venue to announce his next career move after a nerve-racking summer scouring a limited free agent market.
Things couldn't be any more different a year later as they've returned for Sunday's race.
It's Bowyer who is now a title contender, while Edwards is stuck in neutral after a steep drop-off.
Edwards is 15th in the standings and stuck in a 64-race winless streak.
Bowyer is fourth in the standings, 28 points behind leader Brad Keselowski.
