John Madden has passed away at the age of 85. The NFL said Madden died unexpectedly and did not detail a cause.

Madden had a decadelong stint as the coach of the Oakland Raiders, making it to seven AFC title games and winning the Super Bowl following the 1976 season. Madden compiled a 103-32-7 regular-season record, and his .759 winning percentage is the best among NFL coaches with more than 100 games.

Madden retired from coaching at the age of 42 and went on to become an even bigger name as a broadcaster and as the namesake for the Madden NFL Football videogame.
