The Dirty Dozen were the rookies that made the Dallas Cowboys team in 1975. These players were credited with helping the Cowboys advance to Super Bowl X and were a key foundation of the team's success during the latter half of the 1970s going into the early 1980s, as by 1979 many of these players would have replaced many of the Cowboys' aging starters of the 1960s. The rookies came up with the nickname inspired by the film of the same name, and spent half of the season without shaving.[1]
