Jets WIN.

Fans lose.

Too bad.

As former Jets coach Herman Edwards famously said: “You play to win the game.’’

That’s what the Jets did on Sunday in Los Angeles, where they were 17-point underdogs and beat the Rams 23-20 anyway.

Biggest upset of this NFL season — by a lot.

The perfectly imperfect season now has a blemish. The Jets are 1-13, which kills 0-16 and so, too, possibly the chance to draft Clemson quarterback Trevor Lawrence.

You know how much the Jets care about the conflicted Jets fans who desperately want Lawrence poking out of their Christmas stockings?

Not a damn bit. Sorry. Not sorry.

“Hey, our job is to go out and try to win every week,’’ coach Adam Gase said. “It’s been too long for us to even remember what a win feels like.’’

This one was for Jets quarterback Sam Darnold, who too often this season has looked washed up at 23. Darnold played his best game of the season, completing 22 of 31 for 207 yards and a touchdown with no turnovers against the league’s best defense. He got the ball out quickly and made quick, correct decisions.

“He did a great job,’’ Gase said. “He made the right decisions. There was no panic. He was calm through the entire game.’’

This was for their 37-year-old dinosaur running back Frank Gore, who scored a touchdown on a fourth-and-goal and caught the game-clinching third-down pass, which allowed the Jets to go into victory formation inside the two-minute warning.

“Good thing we had a Hall of Fame running back in there that seems to make the right plays at the right time,’’ Gase said.

This was for Jets safety Marcus Maye, who earlier in the game gave up a Rams touchdown and later in the game let an interception slip through his hands, but in the end helped clinch the game with a huge pass breakup.

“I can’t say enough about Marcus Maye and what he did in this game,” Gase said.

This was for Jets rookie punter Braden Mann, who made a game-saving tackle of Rams punt returner Nsimba Webster on a 34-yard return late in the fourth quarter that looked like it was going to blow this thing up.

“I was standing on the end [of the field] where the returner was coming and there was a lot of green grass,’’ Gase said. “That was an unbelievable tackle by him.’’

This was for every Jets player who has played his butt off this season without reward.

“It’s great to see those guys that excited,’’ Gase said. “They deserve this. They deserved it a while ago. We’ve had a few snatched away from us. To finally close out a game — and against a good team, too — it says a lot about the kind of character we have in this locker room.’’

Rams coach Sean McVay was so moved watching tape of the Jets that he called Gase at 4:15 a.m. West Coast time late in the week to tell him: “Man, these guys, they play hard for you.’’

The Jets did so many good things in this game against a superior opponent, it couldn’t help but leave you wondering where this has been all season.

They got a blocked punt from J.T. Hassell, a recently signed free-agent safety out of Florida Tech who was born with two fingers on his left hand. That led to a 39-yard Sam Ficken field goal and a 10-0 lead.

They got a first career interception from rookie cornerback Bryce Hall and got another Ficken field goal out of that for a 13-0 lead.

They got the 1-yard scoring run from Gore on fourth-and-goal to give them a 20-3 lead in the third quarter.

“Man, it feels good,’’ Gore said. “We finally got one.’’

Gore would later seal the game with that 6-yard reception over the middle on third-and-6.

That came after Maye’s pass breakup on fourth down with Goff trying to connect with tight end Gerald Everett for the game-winning touchdown. Finally, there was the most out-of-place scene of this Jets season: Their offense lining up in the victory formation.

“It’s been a while since we’ve been in that,’’ Gase said.

“Greatest feeling in sports,’’ Darnold said. “To be able to ice a game and know we had it. It was an amazing feeling.’’

The Jets, who lost 40-3 last week in Seattle and 31-28 at home to the Raiders with five seconds remaining the week before, haven’t had a lot of amazing feelings this season. In fact, they’d had none until Sunday.

And they’re not apologizing for their rare chance to celebrate.
