Totally AgreeI don't think so.
Not that Brady isn't great.....but most if not all of the QB's that have been inserted in that system over the years have had success.
Brady makes it easier....because he is talented and acts like another level of coaching on the field, but I believe the "system" they use is the true success mechanism.
Can it be replicated.....theoretically yes. I'm sure many have tried but most haven't been successful. You also have to admire their talent acquisition. They take cast offs from other teams and make them stars in their system.
The Pats have moved well beyond simply Brady.
The true power of the Pats is the ethos of excellence that they have established.
Young ambitious and smart coaches take entry level positions with the Pats because they see it as the best place to grow.
Think about it. When is the last time the pats have replaced a high level coach from outside. It's either a promotion or a former assistant that returns.
It will take the departure of both Belichick and Brady to see them consistently lower their orbit. Simply because those to men are so exceptional that they can't be easily replaced.
