JACKSONVILLE, Fla. — These are the types of games where the defensive coordinator isn’t allowed to board the team plane home.

Take flight with the Jets

Text with Brian Costello all season as he brings Sports+ subscribers the latest Jets intel from on the field and off.

Two weeks ago, a report surfaced that Giants defensive line assistant coach Bryan Cox was angry about the seating assignment on a team plane home from New England — and was subsequently fired.

In the case of Jets defensive coordinator Steve Wilks following his team’s 48-20 loss to the Jaguars on Sunday at EverBank Stadium, where Wilks’ seat was located on the team charter back to New Jersey was the least of his worries.

After his defense allowed the Jaguars to score on eight of their first nine possessions, Wilks even being given a seat for the ride home was a minor upset.

But no one was going to get fired after this defeat, the Jets’ 11th loss in 14 games, because this season has drifted aimlessly into a sea of apathy.

So, why bother to clean up the mess now?

Any house cleaning Jets rookie head coach Aaron Glenn will do — and there will be a lot — almost certainly will wait until this season comes to its merciful end.

And that can’t come quickly enough.

Remember when the arrow was pointing at least slightly up for the Jets, who’d won three of five games?

Distant memory.

The Jets lost 34-10 to the Dolphins a week ago at home.

And then there was Sunday, with Jaguars quarterback Trevor Lawrence toying with the Jets defense like a cat does with a defenseless mouse, throwing a career-high five TD passes and running for another.

The 48 points were the most the Jets have allowed in a game since 2021 and the most the Jaguars had scored in a game since 2007.

For those of you scoring at home, the Jets defense has allowed 82 points in the past two games and Sunday was the ninth time this season they’ve yielded 27 or more.

Glenn, after the game, did not sugarcoat what the past two weeks have been, which is nothing short of a colossal setback.

“Yeah, it has been,’’ he conceded. “Because, you just don’t give up that many points and lose by that margin and say that it’s not. Man, we have to figure something out. We can’t lose games like that. It’s unacceptable.’’

Unfortunately for the Jets, unacceptable has become accepted. So, too, has a lack of accountability in some corners of their locker room.

Two of their most prominent defensive players — edge rusher Jermaine Johnson and linebacker Quincy Williams — declined to speak to reporters after the game.

They both were as culpable in this defeat as anyone. Johnson was credited with two tackles and never got a hand on Lawrence. And Williams was the nearest defender on all three of running back Travis Etienne Jr.’s TD receptions.

“Not today,’’ Johnson said when asked by The Post to speak about the game.

“I have nothing positive to say, so I’m not doing any media,’’ Williams said.

Bad form and a bad look.

Safety Tony Adams was one defensive player who spoke to reporters, and when he was asked about Lawrence’s five TD passes, he sounded bewildered and said, “How many?’’

Exactly.

When Glenn was asked if he would consider taking over the play calling on defense, Glenn said, “I know the question is going to be asked, but I brought Wilks in for a reason and I want him to run his system.’’

His system?

What exactly is his “system?’’

The Jets produced no sacks and only two quarterback hits on Lawrence, who’s notorious for holding onto the ball too long trying to make plays.

“It’s hard to explain,’’ Glenn said when asked for an explanation of those two damning stats. “Especially knowing that [Lawrence] is a guy that’s going to hold the ball, he’s going to try to play hero ball.

“We have to do a better job of getting to the quarterback and making sure we get hits on the quarterback, and we did not do that today. So, it’s really hard to explain that. That’s part of the reason I’m somewhat pissed.’’

There’s a lot to be pissed off about if you’re Glenn.

“When you give up that many points, that’s tough,’’ he said.

Glenn’s message to his players inside the locker room?

“You’re a man with some pride, right,’’ Adams said. “It’s going out there and being able to understand that it’s bigger than you.’’

Yet, the Jets keep coming up small — particularly on defense.

“We have three games left for our guys to go out there and play, and I will tell you this: It’s not [just] about the Xs and Os,’’ Glenn said. “Across the board, it’s about the character of the men on this team. I’m evaluating everything. I’m evaluating the schematics, I’m evaluating the Xs and Os, I’m evaluating the players, the character of this team.’’

The rookie coach has got a lot on his hands. More than he probably ever imagined when he was brave enough to pursue this job in the first place.
