Belicheck was where Fisher was 15+ years ago but at some point, he realized that offense mattered. Since that time, he has put together great offenses and it doesn't matter if it is Brady, Matt Cassell (going 10-6), or this 3rd stringer that played tonight to lead the team to a 3-0 record without Brady.
Today he wins with 3rd string QBs and puts up 20+ points. He is actually an excellent offensive mind and tweaks his system each year or sometimes during the year and always has the defense guessing.
Fisher, on the other hand, is so stubborn and wants to prove he can win with the Stone Age approach.
Keep it simple doesn't mean keep it predictable.
I hate to admit it, but part of me thinks this great Patriot start is a good thing so we can get concrete evidence that the Patriots offensive success if much more than Brady and we can stop this oh, Fisher doesn't have the QBs talk.
