DENVER — Robert Saleh would never admit to it in public, because it would contradict his head-coach-speak mantra about no one game being more important than another.

But if the Jets head coach were to have some truth serum sprinkled into his Monday morning coffee, it’s likely he’d tell you that Sunday’s 16-9 survival struggle of a victory over the Broncos at Empower Field at Mile High is the one he’s most proud of among his team’s five wins this season.

That’s because the Jets won while overcoming a great deal of adversity along the way and they didn’t blink. They stayed the course despite losing three key offensive starters to injury in the first half.

Games like this one are the very games the Jets have to win if they’re going to continue to venture into the unfamiliar territory where the NFL contenders roam as November approaches.

The ugly games. Games when you lose key players to injury. Games when your better players don’t have their best stuff.

“This is the kind of game that, when you look back at the success of a season, it’s attributed to grinding out wins like this,” tight end C.J. Uzomah told The Post. “Winning these tight games is huge for morale and momentum.”

The Jets haven’t had morale this high and momentum this strong in years.

They survived the scrappy Broncos in a game that was light years from artistic. But who cares? The Jets are 5-2, their best start since 2015.

No apologies for winning.

“You got to find ways,’’ Jets veteran left tackle Duane Brown said.

“It’s hard to win in this league,” Saleh said.

The victory was the Jets’ fourth consecutive win — the first time they’ve done that since 2015. They’re 4-0 on the road for the first time since 2010, which happens to be the last season they qualified for the playoffs.

Playoffs? Are we talking about playoffs?

“This shows we have a little bit of dog in us,” running back Michael Carter said.

The surprising Jets have won games in several different ways this season.

They won a couple via the breathtaking comeback — the miracle in Cleveland, where they needed a lot of help — and at Pittsburgh, where they scored two fourth-quarter touchdowns to win.

They won one in resounding fashion, smoking the Dolphins at home a few weeks ago.

And they won last week at Lambeau Field, where they smacked Aaron Rodgers and the Packers around in what — to date — is their signature victory of the Saleh era.

On Sunday, the Jets won a game in which, before halftime, they were decimated by key injuries.

Rookie running back Breece Hall, who’s been on a fast track to Offensive Rookie of the Year and has been the Jets’ best, most consistent and dynamic offensive player, was lost for the game (and likely the season) with what the team believes to be a torn ACL suffered in the second quarter.

Invaluable offensive lineman Alijah Vera-Tucker, who was playing right tackle (his third position on the line this season), injured an elbow in the second quarter and didn’t return.

Receiver Corey Davis hurt a knee in the second quarter and didn’t return. That left the Jets thin at receiver, with Elijah Moore back in New Jersey in timeout after his trade-me tantrum last week.

“I didn’t even know what was going on, but I’m just in the huddle like, ‘Where they at?’ ” quarterback Zach Wilson said of Hall, Vera-Tucker and Davis lost around the same time. “We just have to keep moving forward. I said a little something in the huddle — I don’t feel like I needed to — but I said, ‘Listen, take advantage of this opportunity. Step up. Grow a pair.’

“I think the guys got the message. Guys stepped up, saw it was their opportunity and that this is where more money, more playing time and other things come for people. That was really cool when the guys stepped up right there.”

The Jets won the game scoring one offensive touchdown — Hall’s electric 62-yard run in the first quarter — and while also committing 11 penalties. They got three field goals from kicker Greg Zuerlein, who’s quietly become quite the consistent weapon.

They were again the better team than their opponent in the fourth quarter, an impressive trend that’s been building this season, having outscored opponents 74-20.

“I just felt like we were really alive in the fourth quarter,” Saleh said.

“We get excited when it’s the fourth quarter,” cornerback D.J. Reed said.

“The biggest thing is we’re super-hungry,” safety Will Parks said. “We’re not the same. We’re not the same Jets, bro.”
