There has never been a Major League baseball team to go undefeated in a season.
The Dolphins

In the 2009 season: the Colts and the Saints. First time in NFL history two teams have been 12-0 in the same season.
They were in the 2009 season if you mean have they ever beat the three teams in their division twice.
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.
No, the season is long. The best teams lose about a third of the time. Even the worst team can beat the best team sometime during the season.
