After fulfilling a four-year Navy commitment, Staubach joined the Cowboys as a 27-year-old rookie in 1969. He wasn't named the full time starting quarterback until 1971, beginning nine years as the leader of the Cowboy attack. During those nine years, Staubach led the Cowboys to six NFL Championship Games, four NFC Championships, and two tiles. His elusive running style and never-say-die attitude earned him the nicknames "Roger Dodger" and "Captain Comeback."
