FOXBOROUGH, Mass. (AP) — Six-time NFL champion Bill Belichick has agreed to part ways as the coach of the New England Patriots, bringing an end to his 24-year tenure as the architect of the most decorated dynasty of the league’s Super Bowl era. Belichick became just the third coach in NFL history to reach 300 career regular season wins, joining Hall of Famers Don Shula and George Halas. Belichick trails only Shula for the record for victories by a coach. But this season was Belichick’s worst in 29 seasons as an NFL head coach.
