‘Walking on a dream, baby!’ Inside the Chris Jones party after Chiefs’ win in L.A.

A 6-foot-6, 310-pound man in the corner of the Chiefs’ locker room has just earned a $1.25 million check for about two hours of football —or actually just one play, depending on how you look at it.

And if you’ve ever wondered what it’s like for a millionaire to add another million to his bank account, well, it’s pretty much the party you’d imagine.

Welcome to it.

Chris Jones has the DJ rights in the room, just about an hour after he recorded a sack in the Chiefs’ 13-12 win here Sunday, earning the contract bonus earmarked for reaching double digit sacks in a season. For the moment, he’s turned the speakers loud enough that you’ll need to utilize text messaging to converse with the person nearest you.

“Hold on,” he says as he looks toward the contingent of media, “I got a song for you.”

The iPad atop the shelf has his attention next, his index finger cycling through a playlist and finding it quickly.

The keyboard resonates first, and Jones beats the lead singer to the opening line.

“Walking on a dream, baby!” Jones says.

The 2008 electronic single from Empire of the Sun blares through the room, prompting defensive line coach Joe Cullen to peek his head around the corner.

“Hey, that’s Chris Jones’ song!” Cullen shouts.

“Hey, Joe, that’s for you, baby,” Jones replies. “We walking on a dream.”

A few lockers away, a collection of teammates, all defensive linemen, are dancing, bobbing their heads or a combination of the two as the song reaches the chorus.

That’s when we’re treated to the falsetto.

“Is it reaaaaaaaaal now?” Jones belts out, before turning back to the throng of waiting media.

The interview can now apparently start.

The start. That’s where we should proceed, too.

The first image of Jones this season sandwiched him between his agents on opening night as part of an ongoing holdout. We can’t ignore that if Jones played in that game, a meaningful one that the Chiefs would lose, his 43 snaps Sunday outside Los Angeles, in a meaningless game, would have been unnecessary.

Truth be told, they still weren’t necessary in the regular-season finale — the Chiefs were already locked in as the No. 3 seed in the playoffs. They rested most of their starters, or at least as many as they could, which included quarterback Patrick Mahomes and tight end Travis Kelce.

That they allowed Jones to play should be construed as a gift. An expensive one that will cost them not only the cash but the money against the salary cap.

The return? The Chiefs need that Chris Jones — the one who treated every play Sunday like it was his last — in the game(s) that await this month.

Because Jones, a three-time second team All-Pro, reached another level against the Chargers. With some help, to be sure. Defensive coordinator Steve Spagnuolo dialed up blitz packages to ensure the Chargers had no choice but to leave him one-on-one.

“We were trying, man,” Spagnuolo said.

And we were, at long last, able to witness how single-teaming Jones might play out.

Un-good.

Jones generated 13 pressures, per Next Gen Stats, which added that number ties the most from any player this season. Maybe the Chiefs should attempt to design his next contract full of incentives, right?

We have long understood the true value of Jones to be hidden from the numbers — to be better understood by the film that shows him needed to beat two and three players to win a rep. No one in football saw more double teams than he did a year ago.

The scheme let him loose on Sunday.

And proved that theory right.

It might’ve required two-plus quarters to get a sack, but he in the backfield from literally the opening series. He was only supposed to play one quarter, by the way. That’s all his head coach, Andy Reid, had guaranteed him. Then he offered him one more quarter. And then just one more drive.

Eventually, Jones thought he had just one more play — a 3rd-and-6 at the Chiefs’ 14-yard line with about five minutes left in the third quarter.

But let’s back up a handful of snaps. The trainers came out to check on Chiefs rookie Chamarri Conner earlier in the drive, and the break allowed Jones to see the man he needed to take to the ground. The man who had been face-to-face with Jones all afternoon but had refused to let take him down.

Chargers quarterback Easton Stick.

“I’m gonna keep chasing your (butt) until I get my half (sack),” Jones said.

Stick’s response, as Jones recalled: “I know. I know.”

“And I was like, I’m gonna get your (butt) soon.”

He got him.

He got the $1.25 million.

And his teammates got a little something too. You couldn’t help but notice the reaction from the Chiefs’ sideline when the sack came. Jones would reach nearly 15 mph on his sprint over to greet them (Next Gen Stats graced us with this stat). Thanked Spagnuolo for the game plan that pried him free all afternoon. Thanked Reid for the playing time.

But for much of everyone else? They were thanking Jones.

Earlier this week, Jones had informed the defensive line that he wasn’t the only one with some incentive. If he reached 10 sacks — he finished with 10 1/2, technically — he’d buy each of them a new Rolex watch.

“I was lit because we just got a Rolex,” rookie Felix Anudike-Uzomah said. “He told us we’d been working hard this season and that it was for all of us.”

Spagnuolo has one coming. Cullen, too.

Oh, and he’s buying himself too.

With the money he probably could’ve already earned had he not skipped training camp. That’s real. I get it. Can’t bypass that.

But on Sunday evening, hands in the air, it was clear: That won’t stop the party.
