The Steelers drafted "Mean" Joe Greene fourth overall in 1969. In his rookie season Greene was named NFL Defensive Rookie of the Year and was invited to his first Pro Bowl. This was the first of many accomplishments for Greene as he became one of the greatest defensive tackles of all time. He was the centerpiece of the legendary Steelers "Steel Curtain" defense. Greene is a four-time Super Bowl Champion, has two Defensive Play of the Year titles, 10 Pro Bowl nods, and was named NFL Man of the Year in 1979. The Ford Hometown Hall of Famer returned to the University of North Texas to celebrate his achievements and speak to his alma mater in the video above.
