It's said one man's trash is another man's treasure, and maybe the same thing can be said about someone getting fired. One closed door is another opened one? Eh, doesn't quite have the same ring to it.

Anyways, it's Black Monday for the NFL, which means it's time for coaches to clean up their resumes and send in their applications for a handful of head coach positions.

1. Cincinnati Bengals

Though Columbus is closer to elitefts headquarters, Cincinnati isn't all that far off, either, so some of the area strength and conditioning coaches might want to try to fill in for former head coach Marvin Lewis. It won't be an easy role to fill in.

Even though Lewis is the winningest coach in franchise history, the Bengals let him go after a third failure to hit that postseason. Sixteen seasons wasn't enough, though Lewis and the Bengals have said that Lewis leaving the team was a mutual decision.

2. New York Jets

The Jets had a pretty... not pretty season, finishing the season with 4-12. Makes sense that former head coach Todd Bowles was fired mere hours after the Jets' last game.

3. Miami Dolphins

Head coach Adam Gase contributed a 23-25 record for his first three seasons with the Dolphins. The 2018 season looked promising for the Dolphins with a 3-0 start, but just not promising enough with a 7-9 end.

4. Denver Broncos

Expectations were high with the Broncos, which also explains why head coach Vance Joseph was fired after the team's first consecutive losing seasons since 1971-1972. That's an ugly stain on a fairly pristine record. So, uh, no pressure to any job applicants, right?

5. Tampa Bay Buccaneers

Like the Broncos' Joseph, the Buccaneers' Dirk Koetter was fired for a consecutive season loss... but significantly less pressure for applicants, especially since the Buccaneers have missed the playoffs for 11 seasons in a row. (Ouch.)

6. Green Bay Packers

Seniority does not save a coach's skin. Tenure? Who's that? NFL team owners don't know her.

The first casualty of the 2018 season, head coach Mike McCarthy was fired after coaching for more than 13 seasons. Why? An ugly loss at home against the Arizona Cardinals. That game cut the Packers short of a postseason game for the second year in a row. Still, McCarthy's overall track record was pretty good at 125-77-2.

7. Arizona Cardinals

You'd think that beating the Green Bay Packers and essentially getting a head coach with 13 seasons under his belt fired would be enough to keep your job... but it's not.

The Cardinals will not miss Steve Wilks. This head coach survived one season, though "survived" may be too kind a word after a 3-13 season that tied with the worst season since 1988. Under Wilks, the Cardinals' offense withered away into a dead husk of its former self, aka the worst offense in the NFL's 2018 season.

I don't think anyone's going to want to hire Wilks anytime soon, but hey, if anyone can get do better than one of the worst-ever season and offenses, the Cardinals might just hire them.
