Maybe. Historically it has take 3-4 guys to bring him to the ground. As fun as that has been to watch, it is his downfall because he takes a massive beating and ends up on the DL with surgery.
My point is this team is not what it is likely to be by say, week 10 or so. BB will find some way of making the O line protect Brady and the entire defense will improve to averae at worst. Which is usually good enough to take them to the AFC championship game.
If one or both of these things does not happen I will be pretty surprised. And in that case, this team is going nowhere this year.
There are other problems but they can be covered up and compensated for much easier.
None of what I have said is just opinion since we have all seen these things happen several times over the last 16 or so years.
What other teams are ultimately up against is the best football ops personnel in the league and that is not changing anytime soon.
