John Madden, the NFL coach, broadcaster and namesake for the billion-dollar video game franchise, died Tuesday at 85-years-old. According to ESPN, Madden died unexpectedly but did not disclose the cause.

"On behalf of the entire NFL family, we extend our condolences to Virginia, Mike, Joe and their families," NFL Commissioner Roger Goodell said in a statement. "We all know him as the Hall of Fame coach of the Oakland Raiders and broadcaster who worked for every major network, but more than anything, he was a devoted husband, father and grandfather.

"Nobody loved football more than Coach. He was football. He was an incredible sound board to me and so many others. There will never be another John Madden, and we will forever be indebted to him for all he did to make football and the NFL what it is today."

Madden's achievements include winning 16 Emmy Awards for outstanding sports analyst/personality, and covering 11 Super Bowls for four networks from 1979-2009, as well as having a popular football video game named after him.
