In 2007, the New England Patriots went 16-0, becoming the first team in NFL history to go undefeated over the course of the regular season since the league went to a 16-game schedule in 1978. The Pats joined the 1934 (13-0) and 1942 (11-0) Chicago Bears and 1972 Miami Dolphins (14-0) as the only undefeated regular-season teams ever.
