The Jets may or may not climb out of this abyss in which they’re mired — 11 years and counting without a playoff berth.

If they don’t, though, even the most embittered fans shouldn’t blame C.J. Mosley, because the Jets linebacker may die trying to put an end to the losing before his time is up here.

There may not be a player on the team who takes this thing more seriously than Mosley, a team captain in his eighth NFL season, third with the Jets. There definitely isn’t a player on the team who takes leading as seriously as Mosley does.

This has driven him to turn to his father, Clinton Mosley Sr., for advice on how to lead. Mosley’s father worked for years in shipyards all along the Gulf Coast, from Mobile, Ala., to Mississippi before finally earning a supervisor position later in life.

“The ups and downs we’ve had this season have really made me get to know myself more as a person and a leader,” Mosley told The Post after practice Wednesday. “This is the most I’ve talked to my dad about the leadership role and things to say and not to say and how to react.

“He told me when he switched to supervisor, a lot of his guys were kind of on him because he was getting on them for getting lazy. So, his best friend told him, ‘Hey, sometimes you’ve got to let people know what your mindset is on what kind of establishment you want to run.’

“That kind of hit me, because I’m in a position where I can be a player that goes out and does his thing on the field and just chills and lets things go and gets through the season. But I know what kind of team I want to be on and I know what kind of player I want to be, so when I do see things or something not going right, I’ve got to be the one to step up. I’ve been chosen by my peers and my coaches to do so.”

Mosley has made 30 tackles in the past two games and has 118 this season, but that’s the least he’s done on the scale of importance for the franchise.

“When he speaks, everybody shuts up and listens,” tight end Ryan Griffin said Wednesday. “He doesn’t say a whole lot, but when he does speak it means something and everybody stops and listens. He’s an OG and a hell of a player in this league.

“When he came in, he already had the pelts on the wall. He came from a playoff and Super Bowl contending team [the Ravens from 2014-18]. He brings that pride and fire and pushes everybody else to his standard.”

Mosley speaks up only when he feels moved to do so, not simply because he’s a captain and one of the few veteran leaders on the youngest team in the league.

“I don’t like to talk a lot,” he said. “I don’t want to be the one who’s always talking. Then nobody’s going to be listening.”

Running back La’Mical Perine has a unique perspective on Mosley, because he went to the same high school in Mobile as C.J. did, and where Mosley’s younger brother, Jamey, was Perine’s quarterback.

“What you all see out here, that’s not fake,” Perine said Wednesday. “He’s trying to build this team, build a winning culture, because he knows how to win coming from Alabama and playing in Baltimore and being a Pro Bowler. That’s the kind of guy you want on your team to win games.”

Indeed, the Jets could use a few more Mosleys on the roster to “flip” this thing, as head coach Robert Saleh keeps insisting he’s going to do.

The cynic can argue that the five-year, $85 million contract Mosley signed with the Jets, that paid him $51 million guaranteed, is all he needs. But those who know him best understand the winning in New York drives Mosley like nothing ever has since he turned pro. He burns to be a cornerstone of turning this program around.

“Every time you hear him speak, 100 percent I feel that,” safety Ashtyn Davis said.

Mosley said he “feels the vibe of the fans,” who are frustrated with the decade-plus of losing.

“To be honest, if I’m talking to the Jets fan, I don’t think there’s anything I can say to make them believe, because they’re not the ones that are going to be in the building with me every day,” Mosley said. “I need the men in our building to believe that we’re going to change things, and once that happens it’ll start clicking like it never has before. That man next to me believing? That’s all I need.

“Sometimes I get chills. Because when it changes and when things are right, it’s going to be all worth it, man.”
