Trivia: Which team had the only perfect season in NFL history?
2007 New England Patriots
2019 Kansas City Chiefs
1942 Chicago Bears
1972 Miami Dolphins
The correct answer is 1972 Miami Dolphins
So why is this answer correct? : The ‘72 Dolphins aren’t the only team with a perfect regular-season record — that’s been done several times, most recently in 2007 by the New England Patriots. But the Patriots went on to lose Super Bowl XLII to the Giants. The ‘72 Dolphins are still the only team to go undefeated in the regular season and win a Super Bowl in the same year.
