Charles Edward Greene, known as “Mean Joe” Greene, (born September 24, 1946) is a former all-pro American football defensive tackle who played for the Pittsburgh Steelers of the NFL. Throughout the early 1970s he was one of the most dominant defensive players in the National Football League. He is considered by many to be one of the greatest defensive linemen ever and was the cornerstone of the legendary “Steel Curtain” defense. He is a member of the Pro Football Hall of Fame and a four-time Super Bowl champion. His nickname, "Mean Joe Greene" stems from his alma mater, the University of North Texas' athletic teams, which are nicknamed the Mean Green.
