As head coaches, they combine for 718 games of coaching experience, 452 total wins and seven Super Bowl titles. One of them has already been enshrined into the Hall of Fame, the other will join him five years after he decides to retire as head coach of the New England Patriots: Bill Parcells and Bill Belichick are two of the most successful coaches in pro football history.
They not only share the same first name but also 14 years of working together. As was announced yesterday, ESPN in cooperation with NFL Films has made a documentary about those 14 years and how they have shaped the two men since then: 30 for 30: The Two Bills.
