Black Monday, the NFL's annual post-season day of coach and/or GM firings, got its start on Sunday, as news broke the Tampa Bay Buccaneers fired head coach Dirk Koetter. Elevated to the top job in 2016 because they wanted continuity with Jameis Winston, Koetter went 9-7 his first year and followed that up with back-to-back 5-11 seasons after today's loss to the Atlanta Falcons as Winston and Ryan Fitzpatrick combined to throw 26 interceptions, well more than any other team had.
Later on Sunday, the New York Jets fired head coach Todd Bowles. Like Koetter, Bowles went 10-6 in his first season as head coach and failed to post more than 5 wins in any later season, going 5-11, 5-11, and finally 4-12 with today's season-ending blowout loss to the New England Patriots. Sam Darnold gets a new regime for his second season, and GM Mike Maccagnan's search for a new boss will presumably be focused on maximizing his potential.
In other coach and front office news, the Jaguars after their season-ending loss to the Houston Texans announced head coach Doug Marrone, general manager Dave Caldwell, and actual decision-maker Tom Coughlin would all be returning for 2019.
Updates to come on this XP as news of additional firings and non-firings comes later Sunday and on into Monday.
MONDAY UPDATE 10 am: Three coach firings have been announced so far on Monday morning. Steve Wilks will be fired after only one year with Arizona, albeit it one year as the worst team in the league. Denver fired Vance Joseph after two years, the first back-to-back losing years for the franchise since the early 1970s. And the Miami Dolphins fired Adam Gase after three years. Gase is a well-regarded young offensive mind who will probably be considered for one of the open jobs.
And now... the big news, the axe finally fell on Marvin Lewis after 16 years (and no playoff wins) in Cincinnati. It's been three straight losing seasons. They couldn't possibly replace Lewis with Hue Jackson like all the rumors say, right? What a terrible move that would be.
Also, notice there have been no GM firings yet. Only head coaches.
MONDAY UPDATE 12:30 pm: We've got our first GM firing, as Miami's Mike Tannenbaum has been "reassigned within the organization" and Chris Grier will take over full GM duties.
Also, while Atlanta is keeping head coach Dan Quinn, they've fired offensive coordinator Steve Sarkisian, defensive coordinator Marquand Manuel, and special teams coordinator Keith Armstrong.
