Each year, every football team sets out to play a perfect season. Only one has ever succeeded in beating the odds. The Miami Dolphins of the late 1960s were a laughingstock, a franchise where careers went to die. Then came Coach Don Shula. In just a few short years?through hard work, long practices, and his no-nonsense attitude?Shula transformed the team into a championship franchise. Led by such greats as Larry Csonka, Bob Griese, Nick Buoniconti, Larry Little, Mercury Morris, and Jake Scott, the team was undefeated in the 1972 regular season and went on to win Super Bowl VII. Along the way, the Dolphins became the team of the 1970s, with Miami as a fascinating backdrop. Based on years of research and interviews, Undefeated, by award-winning journalist Mike Freeman, examines what is perhaps the single greatest accomplishment in team sports history: the unforgettable season in which the Dolphins didn't lose a single game. There has never been a football team like those Miami Dolphins, and there may never be again.
