Never, The Patriots in '06 went undefeated all the way and lost the Superbowl, They have never before been undefeated in regular season.
During the 2007 season they went undefeated in the regular season before the New York Giants beat them in the Super Bowl
New England Patriots
Yes. In 2007, the Patriots finished 16-0.
Yes, because they are out for revenge (and obviously win the superbowl)
Only 2 teams have ever gone undefeated. The 1974 dolphins and 07 patriots.
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.
The 72' Miami Dolphins went undefeated in a 14 game regular season and then went on to win the Superbowl. The 85' Chicago Bears were in line for an undefeated season and suffered their only loss to.... the Miami Dolphins! The 2007 New England Patriots went undefeated during the regular season, the only team to do so with a 16 game schedule, and would eventually lose to the New York Giants in the Superbowl.
So far, only two: The 1972 Miami Dolphins and the 2007 New England Patriots, the only two NFL teams to have an undefeated season. The Dolphins won 14 games to claim an undefeated season, while the Patriots became the first team to go undefeated in a 16 game season. For the 2009 season, two teams could be added to that list: The Indianapolis Colts (currently 14-0) and the New Orleans Saints (currently 13-1). Only three teams in NFL history have started the season 14-0, and those include the 1972 Dolphins, the 2007 Patriots, and the 2009 Indianapolis Colts.
Once, following the 1972 season, the Miami Dolphins won the Super Bowl to complete the first and last undefeated season. In 2007 the New England Patriots went undefeated and went to the Super Bowl but lost to the New York Giants 17 to 14 in a major upset.
1972 Miami dolphins, and 2007 New England Patriots completed a perefect REGULAR SEASON. Both teams remain undefeated til their respective superbowl (SB VII and SB XLII), However, only the 1972 dolphins won the super bowl to achieve a PERFECT SEASON, while the Patriots lost to the New York Giants
One. The 1972 Miami Dolphins are the only NFL team to go undefeated in both the regular season as well as the playoffs. Four teams have had an undefeated regular season, 1924 Bears, 1942 Bears, 1972 Dolphins, 2007 Patriots. With the exception of the Dolphins, they all lost the championship game.
