I disagree.
Listen to the Taron Johnson interview how he loves the challenge of never knowing what type or player/who he will be defending, if Brady can pull it off, it will make of Offense very hard to cover while improving our defense in practice. Similar to what Belichek was also striving for on Defense, make as many players interchangeable as possible.
Will Brady be able to pull it off? It will be difficult, could be a tremendous success or massive failure. One of the reasons why, i believe, that Buillls are always targeting smart players/team captains, people willing to put in the work.
