Miami Dolphins - In 1972 the Dolphins completed the NFL's first and only perfect season, winning every regular season game, two playoff games and Super Bowl VII, defeating the Washington Redskins 14-7. (The 1948 Cleveland Browns had accomplished an undefeated season, but as members of the All-America Football Conference.) During this season, Griese fell victim to a broken ankle in Week 5 versus the San Diego Chargers and was replaced by Earl Morrall for the rest of the regular season, with Griese returning to the field as a substitute during the AFC Championship game versus the Pittsburgh Steelers and would once again start for Miami in Super Bowl VII.
