John Madden, the Hall of Fame coach-turned-broadcaster whose exuberant calls combined with simple explanations provided a weekly soundtrack to NFL games for three decades, died Tuesday morning, the NFL said. He was 85. The league said he died unexpectedly and did not detail a cause. Madden gained fame in a decadelong stint as the coach of the renegade Oakland Raiders, making it to seven AFC title games and winning the Super Bowl following the 1976 season. He compiled a 103-32-7 regular-season record, and his .759 winning percentage is the best among NFL coaches with more than 100 games.
