Yes, the Dolphins in 1972 went undefeated during the regular season and won the Super Bowl. The 1934 and 1942 Chicago Bears went undefeated during the regular season but lost the NFL championship game both seasons.
The Patriots just finished the 2007 regular season undefeated.
The question was "Was there ever and undefeated NFL Season?" If you're referring to a regular season AND championship win...there was only one...the 1972 Miami Dolphins. If you're referring to and undefeated regular season only...four teams have done this...they are:
1943 Chicago Bears
1942 Chicago Bears
1972 Miami Dolphins
2007 New England Patriots
Both of the above answers are inaccurate. The first team to go undefeated through an ENTIRE NFL SEASON and win the CHAMPIONSHIP was the Green Bay Packers in 1929. Curly Lambeau was their coach. The Dolphins were the 2nd team to do it, 43 years later, without resorting to any ties (NFL had tie games in those days and the Packers had 1 tie). The Packers and Dolphins are the ONLY teams to ever accomplish an undefeated NFL Championship.
No, the Steelers have never had an undefeated season. The Steelers best regular season record came in 2004 when they went 15-1.
