His "stats" weren't as good as Manning's in most categories, but he has always had the better coach in every matchup and he's almost always had the better team. The Patriots used to be dominant, no matter who they played, but you're fooling yourself if you think this year they are dominant. That W-L record is impressive, but they have only played one good team (Buffalo - who they barely got past) and one great team (Baltimore - who crushed them). Everyone else has a combined record of 38-61, not exactly what I would call "hard" by any stretch, perhaps the term "cake walk" would fit here.
This is by far the worst offense the Pats have had w/ Brady under center but it is probably the best defense they've ever had, and they've had some pretty good defensive teams. Brady isn't as good as he once was and it's time to realize that. He's been one of the greatest to play the game at any position, but age is starting to catch up to him. Belicheck has built a dynasty in NE and it's the best the NFL has ever seen (ironic since the Celtics are the greatest dynasty in the NBA) - lucky Boston fans.
IMO, Brady has the rest of this year and next year before he really starts to slide. I'd hate to see him play to the point where his defense is carrying him as we saw in Denver for Peyton's last season, but that is the path before him, and we're starting to see the signs of that this year (some would argue last year as well).
