Franchise History of the Miami Dolphins
The Dolphins joined the AFL in 1966 and quickly became one of
pro football's winningest teams. In 1972, the team posted
the NFL's only perfect season with a 17-0 record topped by a
victory in Super Bowl VII. The Dolphins have been perennial
playoff contenders and, since the AFL-NFL merger in 1970, have
compiled the best winning percentage of any team in the league.
