True, but it will need to continue to evolve. The NFL is a cat and mouse game and in the AFCE in particular the Cheats* are one very big and effective cat. Brady has cut up McDermott’s defenses pretty well. At the same time it is impressive what his D has been able to do with essentially no help from the offense and special teams that at least last year were a disaster.
It’s hard to think about what this D might be if they consistently played with a solid lead and a bit of a ball control offense.
