PITTSBURGH (AP) -- Chuck Noll, the Hall of Fame coach who won a record four Super Bowl titles with the Pittsburgh Steelers, died Friday night at his home. He was 82.
The Allegheny County Medical Examiner said Noll died of natural causes.
The Steelers won the four Super Bowls over six seasons from 1974-79, an unprecedented run that made Pittsburgh one of the NFL's marquee franchises.
Noll's 16-8 record in postseason play remains one of the best in league history. He retired in 1991 with a 209-156-1 record in 23 seasons, after inheriting a team that had never won a postseason game in club history.
Noll was a demanding figure who did not make close friends with his players, yet was a successful and motivating leader.
