Taking a stab in the dark at predicting coaching landings, I'll preface by saying I think McDaniels and McCarthy either end up in Green Bay and Cleveland respectively, or not head coaching at all. I'm picking the latter. McDaniels/Rodgers seems like a pairing that could be a disaster, as could McCarthy/Mayfield. I also don't see Bruce Arians coming back. Anyway here goes:
Denver- Vic Fangio, Matt Nagy's best decision of 2018 was keeping Fangio in place, but he's been so successful, that I can't imagine the Bears being able to keep him. Fangio's aggressiveness and scheming ability is 10X as good as Vance Joseph's was, and could make Denver the best defense in the NFL once more. Having Miller/Chubb off the edges with Fangio scheming, would be a nightmare for offenses, and may be the formula for slowing down Mahomes.
Cleveland- Dan Campbell, he's thought of very highly in the NFL, and I think/hope the Browns would prefer more of an up and comer than a retread. He's worked with Drew Brees, whom Mayfield is most often compared to, and comes from the Payton, and thus Parcells coaching tree. I do wonder if Gregg Williams or Freddie Kitchens would be amenable to returning to coordinator roles, as the continuity would be nice, as the Browns finished 5-2 down the stretch, and both losses were to division winners.
Green Bay- Jim Caldwell, this would be an uninspiring hire to many, but look no further than the 2018 Lions as to how valuable he can be, as they took a major step backward without him. Arguably the most important thing for any prospective Packers coaching candidate is to stay out of Rodgers way. Caldwell did that with Peyton Manning, and is already very familiar with the NFC North. I don't see Green Bay making a splash hire, unless they are planning a massive overhaul, and I can't see that happening as long as Rodgers is still there.
Tampa Bay- Eric "sleeping with" Bieniemy, an up and comer, following in the Doug Pederson, and Matt Nagy path of being the OC under Andy Reid. Bieniemy isn't the most experienced candidate, but Tampa seems like a team that could be willing to shake things up. They also have somewhat comparable offensive talent to the Chiefs, that just needs to be coached up some more.
New York Jets- Adam Gase, I truly feel Gase got the short end of the stick in Miami, he greatly overachieved 2 out of 3 years there, basically whenever his QB wasn't Jay Cutler. Making the playoffs in 2016, with a 6-10 caliber team, and going 7-9 this year, with the least talented team in the AFC in my opinion. Gase also seems to have the Patriots number which is something I think the Jets organization, perhaps more than any other, would place extra value on.
Cincinnati- Todd Monkin, this may be a little outside the box, and they might just roll with an embarrassing Hue Jackson or Vance Joseph type, but here's hoping they actually try to improve the team. Monkin did some outstanding work in Tampa this year, with some excellent scheming and play calling. He's clearly an up and comer, but coming from Tampa, may not get the recognition he deserved, and therefore may be available for a team like the Bengals. The Bengals in theory match up somewhat favorably with that Bucs offense on paper, as Dalton>Fitzpatrick, Mixon>any TB RB, Green, Boyd, Ross=Evans, Godwin, Jackson.
Miami- Brian Flores, I'll admit I don't know much about Flores, but this just feels like a Dolphins move. Take a coordinator from a better team, and hope the magic rubs off. This was by far the hardest team to pick a candidate for. There are probably 6-7 realistic options. Flores is at least familiar with the team already coming from New England, and knows a lot of what they need to fix.
Arizona- Kliff Kingsbury, perhaps more so than any team, I feel the Cardinals can afford to make a bold choice this year. Kingsbury is considered an elite young offensive mind on the college ranks, and after the Wilks debacle, Arizona really can do no wrong, especially since many candidates are refusing interviews. Arizona's #1 goal should be to get a QB whisperer for Josh Rosen, so this fits that idea as well.
