Don't you think you're being overly simplistic on this one? It sounds to me like you think that all it takes to win is a good qb and receiving core. What about that stout O line that lets Brady stay in the pocket? Do you think they come cheap? What about that defense that you said played well? Do you think they would have won this game without them? I could go on and on. Belichick is considered the best because no matter what happens he manages to put together a competitive team year after year. He seemingly finds players out of nowhere to fill holes and he gets more out of players than most people expect. This will inevitably come to an end at some point, most likely when Brady starts to decline, but for the time being I would just be happy with the 2-0 start.
Oh yeah and for the record people hate Pats fans because they are everywhere and for all the wrong reasons. It's like any sport though, people like to back winners. It's the easy way out.
