I keep seeing that teams fail b/c they defend the Patriots offense with zone. That is false.
In short, their offense is designed to beat you either way. All that is required of them is to ID the defensive coverage either thru shifts, motions, or both and they excel in doing so. They have built in man and zone beaters, usually one on each side, for each playcall or within their checks and/or audibles.
Basic example would be a zone beater in a Levels concept coupled with a vertical fieldside (NE calls it "Ghost"), and a man beater with double slants -1 fat, 1 skinny to the boundary (NE calls it "Tosser"). So no matter what the defense may try and do, they have an immediate answer.
