GREEN BAY, Wis. — The visual told you all you need to know about these young, brash, fearless Jets, who on Sunday improved to 4-2, having already matched their 17-game win total from 2021. 

The Jets had just bullied the Packers 27-10 at Lambeau Field, where Aaron Rodgers had won his past 15 starts, and there was rookie cornerback Sauce Gardner playfully walking off the field wearing one of those foam cheeseheads that a Jets fan from the stands put on his head … as he inadvertently walked into the Green Bay tunnel. 

Packers receiver Allen Lazard ran up from behind him and slapped it off his head. Gardner, the unflappable fourth-overall pick in the draft, was undaunted by it all, picking his souvenir up off the ground and carrying on, eventually finding his way to the visitor’s locker room. 

“I didn’t even know what was going on,” Gardner said, flashing a diamond grill on his teeth. “I was just enjoying the moment.” 

There’s an unmistakable obliviousness to these young Jets and, quite frankly, it’s fun to watch. 

They had a lot of moments to enjoy Sunday against a perennial playoff team that was favored to beat them by more than a touchdown. 

There was rookie running back Breece Hall doing a “Lambeau leap” into the arms of a pack of Jets fans in the end zone where he’d just completed his dynamic 34-yard touchdown run that gave the Jets a 24-10 fourth-quarter lead. 

There was Jets’ defensive lineman Quinnen Williams spending more time in the Green Bay backfield than he probably spent his own home last week, wrecking the day for Rodgers and the Green Bay running backs with two sacks, a forced fumble and a blocked field goal. 

And then after the game, there was Jets’ head coach Robert Saleh telling his team that had just surprised everyone but the people inside its own locker room: “We’ve got to start expecting stuff like this.” 

The Jets believed all week that they were going to infiltrate Lambeau Field and beat the Packers. On Sunday, they backed their swagger. 

And, the more these Jets get a taste of days like Sunday the more their confidence grows and the more dangerous they become. 

“We’re showing that we believe we can be as great as any team in this league,’’ defensive tackle Sheldon Rankins, who had a big 9-yard sack of Rodgers, said. 

“We have an extreme amount of confidence on this team,’’ veteran left tackle Duane Brown told The Post. “The beautiful thing about the youth on this team is they don’t really care about the perception or the history of what’s happened here. Everyone’s here trying to write their own story. 

“A lot of people didn’t give us a chance to come in here and win, but we knew what we could bring. That’s a dangerous thing for the rest of the league.’’ 

Safety Will Parks, who returned a Micheal Clemons blocked punt 20 yards for a touchdown that gave the Jets a 17-3 third-quarter lead and left the Lambeau faithful stunned and booing the home side, said the belief of the Jets players “makes us very dangerous, makes us very scary to opponents and makes people pay attention to us more.’’ 

“We’re like little gnats. We just keep biting away, keep biting away and the next thing you know we’re going to end up on your field doing our business.’’ 

When the Jets had the ball in the fourth quarter with a two-touchdown lead and ran the ball successfully when the Green Bay defense knew they were going to run the ball and couldn’t stop it, they’d broken the Packers’ will. 

“I could feel it,” Brown said. “It’s a great feeling, an offensive lineman’s dream.” 

The Jets’ defense broke Rodgers’ will, too, sacking him four times and hitting him nine times. 

“You hit any quarterback as much as we were able to hit him and annoy him today, there’s going to be some frustration,” Rankins said. “He was definitely frustrated, but that’s what we want to see. That’s our objective every week — to piss off every quarterback we line up against in a smart, dominant, violent way.’’ 

A few weeks ago, Saleh talked about “taking receipts’’ from those who didn’t believe in his team. To the Jets credit, there was no chest-thumping inside the locker room Sunday. 

“We’re just getting started,’’ cornerback D.J. Reed said. “Winning is becoming normal. It’s expected. We know that we’re special.’’ 

Special was watching Gardner saunter off Lambeau Field with that cheesehead on his dome. 

“I’m definitely not going to ever forget this — this moment,’’ Gardner said. “Tribute to the Jets fans. They put it on my head. I just had to take it and run with it.’’ 

These young, brash and fearless Jets are taking this season and running with it at the moment, and it’s quite a sight to see.
