“You're not going to eliminate concussions. Anytime you hit your head, you have a chance of getting a concussion, in any sport, too. I think we have to learn more about it. Part of it is rules, part of it is equipment, part of it is medical studies, knowing more about the brain.”

American professional football coach and sports commentator

John Earl Madden was an American professional football coach and NFL sports commentator. He coached the Oakland Raiders from 1969 to 1978 and became known for guiding the team through one of its most successful eras. Under Madden, the Raiders reached eight playoff appearances, won seven division titles, and played in seven AFL and AFC Championship Games, including the franchise's first Super Bowl title in Super Bowl XI. He never finished a season with a losing record, and he holds the highest winning percentage among NFL head coaches who coached at least 100 games.
