Miami Dolphins of the early 1970s weren't especially big, quick, or flashy, and they were soundly beaten by Dallas in Super Bowl VI, but they earned their place in history the following year, becoming the only team in National Football League history to go undefeated (17-0). The Dolphins' "No Name Defense" of 1972 gave up the fewest points in the league, while the offense-playing most of the year without Pro Bowl quarterback Bob Griese-relied heavily on the ground game. Running backs Larry Csonka and Mercury Morris ran for over 1,000 yards each (an NFL first). Griese returned for the postseason and led Miami to a 14-7 victory over George Allen's Washington Redskins in Super Bowl VII, completing the Dolphins' perfect season. It was a dilemma no other NFL team had ever faced: How do you improve on perfection? But head coach Don Shula believes that the 1973 Dolphins were even better than the team that went undefeated a year before. In Super Bowl VIII, the Dolphins pummeled the Minnesota Vikings for their second-straight world championship. Americas' Game features exclusive interviews with Larry Csonka, Don Shula and Manny Fernandez (The 1972 Miami Dolphins) and Mercury Morris, Dick Anderson and Bob Kuechenberg (The 1973 Miami Dolphins). Join NFL Films as they recount the stories of the '72 Dolphins' run to 17-0 and the '73 Dolphins' success in defending their Super Bowl title.
