Collision of Wills: Johnny Unitas, Don Shula, and the Rise of the Modern NFL: Gilden, Jack: 9781496206916: : Books

In their seven years together, quarterback Johnny Unitas and coach Don Shula, kings of the fabled Baltimore Colts of the 1960s, created one of the most successful franchises in sports. Unitas and Shula had a higher winning percentage than Lombardi's Packers, but together they never won the championship. Baltimore lost the big game to the Browns in 1964 and to Joe Namath and the Jets in Super Bowl III--both in stunning upsets.
