After 40 years, President Obama honored the 1972 Dolphins at the White House in 2013.
Curly Lambeau was coach for the unbeaten 1929 Packers.
The 2006 Colts, at the White House with President Bush, are the most recent team to be the last undefeated team remaining to win the Super Bowl.

This is a season-by-season breakdown of the last undefeated National Football League (NFL) team. This list indicates the teams who won the most games in a season before suffering their first loss.[1]

The last team in a new season to lose a game has won the Super Bowl twelve times. Before the Super Bowl era, the last undefeated team won fourteen Championship games, four of which were in the AFL. Before playoffs began in the 1933 season, the last undefeated team earned the NFL championship seven times by having the highest winning percentage (ties were not included in calculation). The last team with an unblemished record has made 29 Super Bowl and 26 Championship game appearances.

The Chicago Bears have been the last team undefeated 17 times (the last time was during the 2010 season), and won the Championship 5 times in those years..The next team, the Los Angeles Rams, have been the last undefeated team 12 times as of the 2018 season. The Rams won 2 titles when they were the last unbeaten team. The New York Giants hold the mark for beating the last undefeated team the most times. They have accomplished this 11 times; the last time it happened was in 2010.
