On Sunday, the Carolina Panthers visited the Atlanta Falcons just two weeks after shutting them out, 38-0, with the idea that they'd leave Atlanta with their 15th win in as many regular-season games. It didn't work out that way, as Carolina fell short, 20-13, putting an end to their pursuit of an undefeated season.
But Tuesday marks the eighth anniversary of the last time an NFL team completed a perfect regular season, and the first time a team went 16-0: on Dec. 29, 2007, the New England Patriots beat the New York Giants, 38-35 at the Meadowlands.
