John Madden says three different generations know him by three different names.
To those who remember him leading the Raiders to their first Super Bowl victory, he's Coach.
To those who best remember him as a broadcaster, he's John.
To the millions who play his football video game, he's Madden.
Regardless, at 79, the Hall of Fame coach, broadcaster and pitchman remains a relevant figure in the NFL, especially in his role as a consultant for helping make the game safer. He had significant input when it came to the league's system of medical spotters, who will scan the field for players in distress and this season have the ability to stop the game and direct officials to remove a player for further evaluation.
