Someone please define that system. The Patriots

What is their system ? Many posters are always saying they can pull people out of the parking
lot and be successful, really .Please explain.If it is just a system why doesn't everyone copy it.
It is a copy cat league I have been told. Many a poster here would give their first born for
BB& Brady.We are living a special time in the NFL appreciate it. Stop complaning about it.
I doubt we will every see this again ,even with our great young coach. The end is near ,
this will be Belichick last year IMO
