Too low if you ask me should be Top 3.
Also Bill Belichik is not the greatest coach in NFL History people clearly do not know what that word means. Perhaps in Super Bowl History but not in History. In my opinion he isnt even in the Top 10.
He sucked with the Browns, inherited a reasonably good team from Parcells, has a great Owner, has coached in one of the easiest eras of the NFL, and has innovated next to nothing (other than perhaps how to skirt the rules). Dont get me wrong he is awesome and will be in the Hall of Fame but he is not the best in NFL History by any stretch.
