There are a lot of statistics from Bill Belichick's tenure as New England Patriots head coach, now in its 22nd season, that underscore why many NFL observers believe he's the greatest coach the league has ever had.
For example, he has as many Super Bowl rings with the Patriots as he has losses against rookie quarterbacks: six.
It speaks to one of the things Belichick does well as an opposing coach: He figures out your weaknesses and then commissions his assistants to create a game plan that exploits them.
It sounds simple, but if you've watched enough NFL, you know not every head coach does the same.
