The question has been: is Brady the reason for Belichick's success, Belichick for Brady's, or do the two share it equally?
I love Tom Brady, and you can't win consistently in the NFL without a seriously good QB, but the Patriots' success is more Bill's than Tom's. Today's game is Exhibit A. The top players for the Patiriots one year ago would have been, in approximate order, Brady, Gronkowski, Wilfork, Welker, Talib,Vollmer, Mankins, Hernandez, Mayo.
Those were pretty much missing today, and Brady had what would be a C- game for him (which is admittedly, a B- game for almost anyone else), and yet the Patriots still had some chance until late in the fourth quarter. Manning, an exceptionally good QB, aided by great recievers and a wonderful D-line, played at a B- to A+ level the whole game, and yet any of three (four?) badly-thrown long passes by Brady would have kept the Patriots in it. Belichick is indeed a jerk at times, and I doubt I'd like him as a pal. Still, I think he is the central cog.
Because of film, information, training, and PED's, today's game is far superior to the Vince Lombardi, Tom Landry, George Halas eras. Joe Namath, Ron Jaworski, and Roger Staubach have all acknowledged that today's quarterbacks complete passes in games that they could not complete in practice. It just is. Sammy Baugh or Johnny U would have done even better in this era of more advantages, but the cold facts are that they didn't do as well as QB's today. Montana was great, but Rice was an enormous uncredited asset. (uncredited in the quarterback discussion, that is.) Today you saw the two best QB's to date in NFL history. NE fans hate Manning, but I don't. I love his game.
BTW, people up here get torqued off at the fans around the country who keep focusing on Spygate as the big CHEATERS issue, even though it was the coverup more than the crime that caused the $500,000 fine. I'm not so bothered. Like a defense attorney who tries on a ridiculous argument defending a clearly guilty client - well, he has to say something. He can't just capitulate and say "your honor, my client deserves 25 years to life for this." People who hate New England have to give some kind of reason, even a dumb one. If you say "that was years ago, and small potatoes" they aren't going to just reverse field and say "Oh, you're right, I like them now."
