New England Patriots head coach Bill Belichick has the most Super Bowl wins of all time, making him possibly the greatest postseason coach in NFL history. When it comes to regular-season NFL games, though, the greatest of all time is John Madden.

Since the inception of the NFL, no head coach in the game's storied past has a better regular-season winning percentage than John Madden (.759).

After Madden suddenly passed away at the age of 75 on Tuesday morning, Belichick, one of the game's historians, was asked about Madden on Wednesday during the Patriots' press conference and had this to say:

“John is just a tremendous person to be around. I think we all, probably, set out to try to have a good professional career. John had about five of them. He set the standard for coaching in his era. They had the best record, best teams, championships, and all that. Raiders had a great style of play that was very, I’d say, captivating. He, certainly, did a lot for the league and the competitiveness of the league. He was a great champion for minorities and minority scouting. Some of the great players that they had with the Raiders from the smaller black colleges, he and [Al] Davis brought into the organization.” – Bill Belichick

The five careers that Belichick is referencing is the fact that Madden went from playing for the Philadelphia Eagles before he was injured in his first training camp as a pro and was forced into coaching. He then went on to be a college coach for Allan Hancock College and San Diego State before coming into his third profession as the head coach of the Oakland Raiders.

After retiring from coaching, Madden stayed in the game with his fourth and fifth jobs. First, he went into broadcasting and eventually became the highest-paid analyst in the league. Then, he settled into his most financially successful and final career as the name and face of the Madden video game franchise that is approaching 100,000,000 copies sold since 1988.
