WE REMEMBER John Madden – Legendary NFL Coach and Broadcaster Dies at 85 | VIDEO

The league said he died unexpectedly and did not detail a cause.

Madden gained fame in a decade-long 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.

But it was his work after prematurely retiring as coach at age 42 that made Madden truly a household name. He educated a football nation with his use of the telestrator on broadcasts; entertained millions with his interjections of “Boom!” and “Doink!” throughout games; was an omnipresent pitchman selling restaurants, hardware stores and beer; became the face of “Madden NFL Football,” one of the most successful sports video games of all-time; and was a best-selling author.
