Bill Belichick's Patriots legacy: The NFL's greatest dynasty - ESPN
We've officially closed the book on the greatest dynasty in the history of the NFL. The Patriots and coach Bill Belichick parted ways Thursday, ending a tenure that lasted nearly a quarter of a century. In an era in which the league's rules are designed to produce parity and short-term success, Belichick's New England teams went 266-121 and made it to nine Super Bowls, winning six. They had a stretch of 17 division championships in 19 seasons. We might never see another NFL coach put together a two-decade spell like his again.
