Forrest Gregg, who earned the nickname "Iron Man" for playing in a then-record 188 consecutive NFL games during his Hall of Fame career, died Friday in Colorado Springs, Colorado. He was 85. Barbara Gregg said her husband of 59 years died from complications of Parkinson's disease. The former offensive lineman, who was a seven-time All-Pro and nine-time Pro Bowler, played 15 seasons in the NFL with the Green Bay Packers and Dallas Cowboys from 1956 to 1971. Legendary coach Vince Lombardi once called Gregg "the best player I ever coached."
