L.C. Greenwood, part of the Pittsburgh Steelers' legendary "Steel Curtain" of the 1970s, has died. Greenwood was 67.
During his 12-year career, the Steelers won four Super Bowls, establishing themselves as one of the preeminent dynasties in NFL history. Greenwood, a defensive end, was a six-time Pro Bowl selection and a member of the NFL's All-Decade Team for the 1970s. He's also a member of the Steelers' All-Time Team, and his four sacks of Roger Staubach in Super Bowl X were good enough to get him named to the Super Bowl Silver Anniversary Team in 1991.
Greenwood is not a member of the Pro Football Hall of Fame, though he reached finalist status in 2005 and 2006.
