The dance party was moving and grooving to “Knife Talk” by Drake and then really got moving when “Juicy” by Notorious B.I.G. blared out from the speakers in the visitors’ locker room at Nissan Stadium in Nashville.

The Giants came to town and Music City was the setting for their own concert tour after they came back Sunday to defeat the Titans 21-20, marking Brian Daboll’s first game and first victory as an NFL head coach. The tunes were up and Daboll was, well, um, Daboll was, er, he was, well, he was making some sort of physical contribution to the festivities.

“They were dancing before I got in there,” Daboll said on Monday. “I don’t know if I was really dancing very much, if you want to call it that.

“It’s good to celebrate with your guys. They put in a lot of work and I give credit to the players who are out there playing. They had a lot of juice after that game, and rightfully so. They played a tough 60-minute game, had some good plays and some bad plays that you had to bounce back from. They brought me in the circle there. I don’t think I’d call it dancing though.”

Daboll, surrounded by his players, bobbed up and down to the beat, clapping his hands and then waving his arms up and down before tugging on the front of his pullover to accentuate the Giants logo. Closest to him in the celebration were Xavier McKinney, Sterling Shepard, Leonard Williams and Oshane Ximines, all cutting loose like unabashed middle schoolers at a lively Bar Mitzvah.

Earlier, Ximines had lifted up a Gatorade jug and dumped the icy liquid contents onto the shoulders and back of the head coach who decided to give him another chance, a still-young (25) outside linebacker who had been buried by the Joe Judge coaching staff.

“I didn’t even feel it,” Daboll said.

No kidding. So many around the Giants — and especially their most ardent and anguished fans — were numbed by what transpired in Week 1 of the 2022 season. They were down 13-0 at halftime and it was looking like more of the same from a franchise that has grown all too familiar with how the scenario was unfolding.

Even after Saquon Barkley and Sterling Shepard, holdovers from past coaching regimes, scored touchdowns and Daboll boldly went for the two-point conversion, down 20-19, with 1:06 remaining to take the lead there was an impending sense of doom from everywhere except within. An organization that has not created its own luck for more than a decade got some thrown its way when Randy Bullock’s 47-yard field-goal attempt sailed wide left at the buzzer.

If that kick had split the uprights the Giants and Daboll would be 0-1. He told his team a day later if that was the case, he would not have wanted to see anyone with “their heads down to the ground.” He started reviewing the game on the flight home and finished it the next morning. There is plenty, he reported, that needs to be corrected and cleaned up.

“Regardless of the outcome of the game, you’re always coaching the things you need to coach and when you win, the players, you have their ear a little bit more because they’re happy they won the game,” Daboll said. “Certainly when you win there’s a little bit more juice.”

Is it tempting to signify this reversal of fortune with a checkmark in the “improved culture’’ column. Daboll’s way is more easygoing than the harder-edged Judge and players still on the scene from 2020 and 2021 — Barkley, in particular — are enjoying the softer touch. At 47, Daboll is comfortable with himself and has learned from the various successes and failures during the long journey — he started his coaching career 25 years ago — that if he does not connect with those around him it is not going to work.

“Since they first arrived, they showed us we can be ourselves,” linebacker Tae Crowder said. “They preach that a lot: Just be yourself and have fun with it. It’s something they do, too.”

For his first game, Daboll had his wife, Beth, and five of his six children with him in Nashville — Christian was unable to attend his father’s debut because he was busy working on the Penn State football staff.

Daboll, sounding tired a day later, knows there is much work to be done. His guys won a game few outside the circle expected them to win. His huge gamble to go for the win rather than kick the extra point to pull even scored huge ratings with the fans. His players were equally smitten with it but not at all surprised by it.

Daboll, though, cannot stick with the dance moves he unveiled to mixed and bemused reviews.

“We’re going to work on that,” receiver Richie James said. “He’s true to him. That’s who is. He’s a jokester, a good dude.”

The dude is 1-0. Cue the music.
