Still the only undefeated team in NFL history, the Dolphins went 17-0 even without starting quarterback Bob Griese, injured in the fifth game of the season, who returned to lead the Dolphins to a 14-7 win in Super Bowl VII. Six players from the team are now in the Pro Football Hall of Fame.

1979 Pittsburgh Steelers
Known most for its Steel Curtain defense, the '79 Steelers were just as proficient on offense, finishing second in the league in both passing and rushing yards. It was two long pass plays from Terry Bradshaw -- 47 yards to Lynn Swann and 73 yards to John Stallworth -- that led the Steelers to a 31-19 Super Bowl win over the Rams.
