EDIT: Train of thought got away from me a bit. Sorry about that.
Willie Mac, Rodney, Wilfork should go. Probably Seymour. Wilfork could be kept out by his lack of sack numbers, but that's just ignorance.
No one else. And I have to say, this discussion - and the lack of blue chip HOFers across this dynasty with all the championships and constant high levels of performance - is an incredibly strong argument for BB as GOAT HC. And honestly? In the room for the discussion as GOAT GM as well. He's been playing a different game than GMs across the league for decades now - not getting seduced by superstardom, but building depth to plan for the attrition that defines each NFL season. He limited the weak spots other coaches could exploit, and worked to ensure that he has whatever tool he needs to exploit the weak spots of other teams. This strategy got increasingly powerful as the season went along, and tended to peak in the playoffs, when teams weak spots have been exposed by injuries and they have sunk into their "personalities," - a reliance on their own strengths and what has been working for them to get them there. Belichick forced them to play left handed and try to win with their weaknesses. With very rare exceptions, he saved money that most teams spend on their top-tier players to pull together a deep core of second-tier players and third-tier players who were either extremely flexible or could do one or two things at a first-tier level. And most importantly, players who just loved to get dirty, put in the work, and play football.
And no, I don't think he's lost his fastball. If anything he may be a half-notch below his peak performance as a coach - still at least a full notch above the league as a whole - but I don't see that from the GM perspective. Brady's contract (and Brown's) was a time bomb, and he had to absorb that blow last year and clean out some dead weight. He did it, and I think this team is 1) the first step in a 2-3 year rebuilding plan; 2) ahead of schedule; and 3) better than they are being given credit for. The places this team is weak can be covered by their strengths. Defense, a flexible running game, the ability to run to set up the pass and pass out of run formations, a precision/timing passing game, a wide variety of receiving options to take advantage of matchups, smart play that avoids turnovers and moves the sticks, and the ability to take the occasional shot deep and make it hurt...this can cover for dynamic pass-catchers outside the numbers.
So Miami has outside cornerbacks that will take our outside WRs out of the game. Okay. Do they have LBs and safeties that will cover the TEs and RBs? Do they have enough that are good enough in coverage? Do they have enough pass rush to force Mac to make the wrong read, and the playmakers in the middle of the field to take advantage of it? If they have great coverage linebackers and safeties, which kinds do they have? The kind that can really limit Jonnu Smith is not the same kind that limits James White. And JJ Taylor is not likely taken out of the game by the same "backfield coverage specialist" that would cause problems for Stevenson.
There are very few teams that will check all the boxes they need to check to really shut down this offence. That's what this team is built for. It's why Belichick rarely broke open the checkbook to pay for high-end targets for Brady. He paid for Brady because Brady's favorite receiver was the one who was open, and he built the team to take advantage of the matchups his team-building earned for him.
I think we all feel pretty confident that this defense will be strong, and could be special with Gilmore back on the field. I think that this offense will have it's problems, but in the end won't be the crippling problem that so many fear. The offense will score. Not at will, but enough. And they will control the ball, not give opposing offenses extra chances, and ensure the defense has time to rest and isn't asked to do too much.
The 2021 Patriots will be fine. The Dolphins on the other hand...I think they're overhyped right now. A team that is that young and unproven on the OL typically can't be counted on to take advantage of all the weapons they have at their disposal...and I don't think Tua can make up for the difference. Everyone talked about Mac getting the benefit of playing with a team of players that could dominate their 1-on-1 opponents, but Tua had the same thing, and has done much less to prove that the can rise above it. The corners are great, but without the ability to stop the run and shut down the underneath passing game, you might not notice much of a benefit. Jaelan Phillips had better be the real deal, because without him all their pass rushers are undersized and susceptible to being a focus of the run game.
That said, the Patriots might very well lose this game, and they could even lose ugly. It could very well be that this team takes awhile to come together. But I expect the team will get stronger as the year goes along. Which is good, because they're going to need to be at their best for the two Bills games at the end of the year.
