I hate you. You're making me praise New England.
I'd put a good deal of stock in their QB, but moreso in their coaching. For years now they've been prepared for everyone they face and that team is always in a position to succeed based on the game plan going in. I think you're right in that *individually* we match up very well. But as a functional unit, they're light years ahead. We're makings strides since Fisher first took over a mere 2 years ago, but there's still a ways to go before we become the well-oiled machine they're been for well over a decade now. They've had "The Patriot Way" in place since the late 90's. We're in our infancy as it relates to "The Rams Way."
The thing with NE is that Brady allows them to play different types of O. He can do the vertical thing, the conservative thing, the WCO type of thing and any other thing because he is that good. So that flexibility allows the coaches to change more than most coaches have the ability to. A lot of what the coaches can do is related to what Brady is capable of doing. They can game plan around any type of defense.
By himself he gives the coaches a wider array of opportunity than almost any other QB in the NFL. Only the truly elite, meaning top 3 or 4 , offer that.
It's like having Faulk or a player like that (TThomas of the Bills back in the day is what made the K-Gun O work), it adds ways to hurt the defense.
