Bill Belichick's finger prints are all over the game of football. He is without a doubt one of the greatest coaches to ever step foot on a football field at any level.
In Cleveland, he's always given a hard time for having a losing overall record, but analyze that record for a second.
6-10 in his first year there. 7-9, 7-9 in his next two. 11-5 and a play off win in his 4th year. Going into his fifth year, he had the Browns in a place where they were considered to be Super Bowl favorites, and then the owner of the Browns decided that he would announce, before the season began, the move to Baltimore. Under those circumstances, going even 5-11 should be a testament to him, though I'm sure he'd disagree with that assessment. He was then fired and didn't catch on to another head coaching gig until 2000 with the Pats.
He is currently the longest tenured head coach in the NFL.
Belichick assistants who have gone on to become NFL head coaches?
Romeo Crennel, Al Groh, Josh McDaniels, Eric Mangini, Nick Saban and Jim Schwartz. You haven't seen many of those names make huge waves, but all of them were given head coaching positions due to their high level of football acumen, which Belichick undoubtedly had a part in.
Belichick assistants who went on to become NCAA head coaches?
Kirk Ferentz, Al Groh, Pat Hill, Bill O'Brien, Nick Saban, Charlie Weis, Kliff Kingsbury, Pete Mangurian.
All Saban did was win MULTIPLE national titles, and Bill O'Brien is turning around a program that was in need of a crash cart in Penn State.
Belichick assistants or executives that went on to other positions?
Jeff Davidson, Thomas Dimitrioff, John Mitchell, Ozzie Newsome, Scott Pioli, Joel Collier, Mike Tannenbaum, Brian Daboll, Rob Ryan, Brad Seely, Phil Savage, Jim Bates, Chuck Bresnahan, Dean Pees.
He's adapted the Erhardt-Perkins offensive scheme to completely fit his personnel and take advantage of a tremendous quarterback in Tom Brady. He's also helped to mold the Fairbanks-Bullough 3-4 scheme and made it compatable with being a 4-3 scheme.
There is no one better in the NFL to adapting to their personnel than Bill Belichick. And there's a reason for it. His intelligence.
Ask any coach who has ever worked under him, some of whom I HAVE asked personally, and they'll tell you that he may be the greatest football mind of all time. Bill O'Brien is one of the men I've spoken with. I've also read Nick Saban's book, and it's evident that Belichick had a profound impact on his coaching philosophies and schemes.
Belichick is not overrated. I don't understand the logic of anyone who says so. In fact, it's completely illogical to suggest so.
Saying "take Brady away" and he's average is silly. Take Montana and Young away from Walsh. Take RG3 and Elway away from Shanahan. Not many coaches will do what Gibbs did, and Gibbs did it well. He found guys that fit his needs and committed to them. He used his Air Coryell system in conjunction with his smashmouth run game to really aide him, and he adapted, especially in his first run, better than anyone in football.
But don't discount Belichick because he doesn't have many Super Bowl winning quarterbacks. He hasn't needed that many. Gibbs only did it out of necessity. If Gibbs had ONE guy, he would have used ONE guy.
In my biased opinion, Gibbs is the greatest coach of all time, even better than Lombardi and Walsh. But Belichick is NOT far behind.
