Black Monday, the day when N.F.L. head coaches are often shown the door, wasn’t as black this year. But that was only because so many coaches had already been fired.

Doug Marrone of the Jaguars was the first to learn his fate on Monday morning, with the news confirmed in a statement from the Jacksonville owner Shad Khan.

Marrone joined Adam Gase of Jets, who lost his job on Sunday, and three coaches who didn’t even make it through the season: Bill O’Brien of the Texans, Dan Quinn of the Falcons and Matt Patricia of the Lions.

Who Is Out?

Doug Marrone, Jaguars

The Jaguars won their first game of the season against the Colts, launching a wave of Minshew Madness headlines about the triumph of their colorful quarterback, Gardner Minshew. They then proceeded to lose 15 games in a row. That signaled the end of the line for Marrone, the former Buffalo Bills head coach who took the Jaguars to the A.F.C. championship game in his first season, but was 12-36 since. The Jaguars’ 1-15 record will give them the top pick in this year’s draft, a selection they are very likely to use on Trevor Lawrence of Clemson. Farewell, Minshew Madness.

Adam Gase, Jets

Gase was fired Sunday, not long after the Jets lost to the Patriots. The team finished the season 2-14 after an 0-13 start. Gase was expected to be an offensive guru, but he was 9-23 in his two seasons, and the young quarterback Sam Darnold struggled. With the Browns making the playoffs after 17 years, the Jets now hold the longest streak of missing the playoffs, 10 seasons. The next longest playoff drought is five.

Midseason Firings

Three head coaches did not even make it to Week 17.

Bill O’Brien was fired by the Texans after an 0-4 start. O’Brien was 52-48 with four playoff appearances and two playoff wins, but his roster moves as general manager didn’t produce the success needed to keep his job.

Dan Quinn was fired by the Falcons after an 0-5 start. In five-plus seasons, he was 43-42 with two playoff appearances and a loss to the Patriots in Super Bowl LI.

Matt Patricia was fired by the Lions after a Thanksgiving Day loss. In two plus seasons, Patricia was 13-29-1.

Who’s Next?

Four other teams who put up poor records are not expected to fire their head coaches.

The Bengals (4-11-1) got an exciting season out of the rookie quarterback Joe Burrow, but despite that poor record the team said Monday that they would not dismiss Coach Zac Taylor.

Doug Pederson is still revered in Philadelphia for his Super Bowl season and despite some grumbling in his city and his locker room he is expected to keep his job even though the Eagles ended up 4-11-1 in a terrible division.

The Panthers and Broncos were both 5-11 this season, but Matt Rhule and Vic Fangio are likely to stay as well.

The Chargers may be a different story: Although their record was a bit better than those teams, they may fire Anthony Lynn, who followed a 12-4 season in 2018 with records of 5-11 and 7-9.
