Well, so far the biggest shocker is Hue Jackson retaining his job which somewhere out there Rod Marinelli is going "WTF?"
As to the others ...
Well, even though Del Rio came well short of expectations this season after a great 2016 season and a failure to re-elevate Carr's game, this latest talk about trying to correct the sins of the father by bringing Gruden back with an ownership's stake? Mark Davis is really looking like a big buffoon and an embarrassment to the league the way he's brought about this catastrophic Las Vegas move. Crazy thing is, if Gruden gets an ownership stake, he might become immune from ever getting fired because he now has leverage on the team.
Chuck Pagano was two seasons overdue to get fired.
It became pretty obvious Fox was going to be gone in Chicago.
A little surprised Vance Joseph didn't get axed, but my guess is his rope just got shorter.
Not too surprised on Caldwell being that it's Detroit and the Lions haven't shown a lot of progress under the guy.
Marvin Lewis is a dunderhead and has been about 7 years overdue to be kicked out of Cincy. Arians was likely to retire with his health issues, but was a good guy.
Other coaches I'd say are on the hotseat watchlist:
Jay Gruden, Adam Gase, Jason Garrett, and while I don't expect him to be fired, John Harbaugh's seat in Baltimore has to be getting hot after the Ravens who were becoming the favorite of NFLN for being the hottest team in the NFL blew their playoff chance with a bad loss at home against the Bungles.
