I think if New England's job opens up that's the one that will be coveted. However I also think it's 99% likely Jerod Mayo would just get the job if Belicheck moves on. It's hard reading tea leaves from BB in the first place, but a wild guess is from limited media readings is he may just give up nearly all GM duties, and Josh McDaniels will return as OC, with Mayo promoted to full-time DC. Fans of the team need to also remember they have the best cap position in the entire NFL over the next 3 years. They are going to have a top draft pick next year (#3 overall), and a ton of cash to spend on FA to fix their OL, get a WR, a TE, etc. Who does Kraft want leading the team into that future?
The Chargers position has some appeal due to quality players under contract, a new facility, and good weather. The negatives? Dean Spanos hasn't been a very good owner, he's stingy with his money, and too big of a chunk of their salary cap is pegged to one good player, who hasn't quite lived up to that money (yet) in Herbert. Can a new coach change that?
Washington is likely another place someone will want to coach, depending on how the structure is set up. Josh Harris has already proven to be a massively better owner than Daniel Snyder. There is going to also be a lot of support from the league overall for this team to appear in a good light, and very likely a new stadium in the next couple years.
As a Raiders fan I know a lot about their situation. If I were the owner I'd just make Antonio Pierce the HC today (not sure how the Rooney rule comes into play here though), and pour everything into keeping Patrick Graham as DC, and get ready to find a top flight OC. But I also have no clue how Mark Davis thinks. He has a long history of both liking shiny things and splashy hires, as well as making one surprisingly good decision followed by a surprisingly bad one. So who knows?
Carolina is of course the huge question mark. There's no question David Tepper can write the fattest check to whomever wants the job. But who wants the job? Tepper also fired Scott Fitterer as GM (who I can't imagine went kicking and screaming. His desk was probably happily cleaned out days ago). So the question becomes, who's in charge there? Usually a GM hires a coach. But if it's a big name coach, that coach has more GM power and the GM often just works with contracts, cap room, and team business with the team's president. But the team now needs both, this is Tepper, and he's very likely in charge of everything, and everyone will report to him on a daily basis. So no guesses what happens here.
The pressure in Carolina will be extra challenging also because whomever is hired as HC is going to not only be expected to turn the team around fairly quickly, but also develop (fix?) Bryce Young, who didn't show much this year, no matter who was coaching or calling plays, blocking, running routes. This season made his ceiling look perhaps above average as a player, that's it. So the stress of showing that isn't the case, with a limited deck of cards, will be big.
Oh wow, people are going to be freezing. Any drop issue for both teams will only get worse with it being that cold. It’ll come down to who runs the ball better, defense for field position and turnovers, and special teams for converting. With the Dolphins injuries I think Chiefs have a leg up on the overall quality of the defensive side and Chiefs special teams should be better since they practice in it.
I tried again looking up KC games in winter, and Mahomes has played quite well in such games. Not lights out big numbers, but he's done just fine, and I imagine he will here. The question becomes, as you say, drops. But also timing. From what Nomad posted the field should be in very good shape (KC one of the best run organizations in the NFL), so route running shouldn't be too bad, just catching and holding onto a frozen brick.
I still think Miami is going to have even more trouble with this, even if they get some of their offensive players back.
The one plus for this wildcard is the only sure win team looks to be the Bills, every other game it could go either way.
From what I can tell TJ Watt has an MCL sprain and is very likely out for this game, which is the worst news for the Steelers. The "best" news is as I posted before, it's going to perhaps be cold, but very windy in Buffalo. If that holds true, it could turn the game into a running grind, or one where a couple interceptions change things, that could give the Steelers some hope. But Buffalo has been increasingly better at running the ball as well, and with no Watt...
