Really hard to figure out what to do next though. Because it's the NFL you need to keep filling up holes (like, safety is an issue next year if you don't re-sign Dugger, for example; center is becoming an issue fast; you need more good DTs).
If only there was a book on roster construction and team building to help me figure out analytically what the Pats should be doing. OH WAIT THE INCHES WE NEED IS ON SALE NOW.

(it's a new book on the topic and awesome, although I'm only fifty pages in and don't know the secret to team building).
Anyhow regardless of whether you think BB should be given more rope or not building a contender in the NFL is very hard-careers are pretty short, you need a lot of good pieces, it's really really really hard to get a great QB and crazy hard to win without one. Fans like to think that blowing it up works but honestly, that's not some great option because you've got to be mind-bendingly awful to get the first pick in the draft when there's a sure thing available at QB. And I'm not sure that trades like the HIll and AJ Brown trade are going to work out in the end for the dolphins and AJ Brown--there is a ton of money on those deals and the cost in draft picks isn't small for either of them. And then if you don't love Mac, well, I get it but you do have to play someone at QB, letting Mac go and replacing him with Baker Mayfield or whatever for a year so you can stink get a great QB you're about as likely to end up with you being 6-10 picking fifth and grabbing a good tackle prospect (and we'd hate it and the owner loses money with empty stadiums and coaches and the staff get fired). Lets be real for a second, as much as some say Mac isn't the answer having a 3-15 team with Davis Mills isn't some much better answer either--that's an awful year of watching football for all of us.
Honestly the best answer I can come up with is you go with management you trust for the three to five years its likely to take to build up the team from where we are (and to be diligent caretakers after if they do find success-and BB is just about aged out of that in my book), you keep signing Mac but to relatively short money, and you try your best to execute in the draft and free agency and get the pass catchers first and help on the offensive line second with the caveat that if you are within striking distance of Mahomes 2.0 (maybe you love Sanders or JJ McCarthy, I don't know) you get them even if you still have Mac and it undermines him.
