The Broncos rolled out their usual celebratory props in the locker room after Sunday’s win. There was loud music, a disco ball and a smoke machine.

But the celebration was a bit more muted than one might think. Yes, Denver defeated the Los Angeles Chargers 19-3 in the regular-season finale at Empower Field at Mile High to clinch the No. 1 AFC seed and secure a bye and home-field advantage throughout the playoffs. But Denver didn’t manage a touchdown on offense against a team that rested some key players.

Mainly, though, the Broncos know there is plenty of work ahead if they want to attain their ultimate goal of winning the Super Bowl.

“It was a little bit of both,” center Alex Forsyth said of there being a celebration after the game but also a business-like attitude. “It was fun to celebrate with the guys but we know the journey we have and the challenges that are going to come with it.”

After the win, the Broncos looked at what they have accomplished so far this season and what they need to clean up. The Broncos went 14-3, their most wins since they went 14-2 in 1998 with a 16-game schedule.

The Broncos have an extra week to rest before they play at home in a divisional playoff Jan. 17 or 18. If they win two playoff games at home, they will earn a date to Super Bowl LX on Feb. 8 in Santa Clara, Calif.

“It’s significant and the reason is you can see the light,’’ said Denver coach Sean Payton. “Two home wins, and that’s exciting. It’s why you do all of it. It’s why you work late hours. It’s why the players train and lift. It’s a big deal.”

Quarterback Bo Nix shared in the excitement of wrapping up the No. 1 seed.

“It’s the best possible position to be in,’’ Nix said. “Two home games is where we want to be. … It’ll be good to play here because of our stadium and the atmosphere. … It’s like winning a playoff game this week, so it’s huge having that bye and also you get an extra playoff check.”

Nix, though, knows the offense will need to play better in the postseason. The Broncos’ only touchdown came on a 45-yard interception return by Ja’Quan McMillian that gave them a 10-0 lead in the first quarter.

On offense, the Broncos had to settle for four field goals by Wil Lutz. They got only field goals on their three trips to the red zone.

At one point in the first half, Nix yelled at the offense, “Wake up.” But after the game he pointed the finger at himself.

“I should have done a better job today having more urgency in the huddle and getting us going,’’ Nix said. “I felt like I failed us on that. Overall, I thought we didn’t play with the tempo and passion we normally play with. … So, next time we get in that spot, I have to have better urgency and be a little bit of spark myself. The rest of the guys will do the same.”

The Broncos had a conservative attack against an outmanned foe that rested its two top pass rushers in Tuli Tuipulotu and Khalil Mack. Nix completed 14 of 23 passes for 141 yards and was sacked four times. He did rush for a season-high 49 yards on nine attempts as the Broncos overall had just 240 total yards.

Denver’s defense, though, stepped up. The Broncos allowed the Chargers just 217 total yards and bothered backup quarterback Trey Lance into completing just 20 of 44 passes for 136 yards.

Lance started after Chargers coach Jim Harbaugh had announced last Monday that star quarterback Justin Herbert would be rested. The Chargers had clinched a playoff berth and knew they would be opening on the road. They have the No. 7 and final seed in the AFC and will play at No. 2 New England next Sunday night.

Lance was sacked four times as the Broncos finished the season with a team-record 68. Outside linebacker Nik Bonitto had 1.5 sacks. He set a career high of 14, topping last season’s 13.5, when he had a strip sack of Lance early in the fourth quarter.

“We got to keep playing our best ball and show up in the playoffs and that’s what we plan to do,’’ outside linebacker Jonathon Cooper said of the defense.

Cooper lauded the play made by McMillian, calling him a “beast.” With the Broncos leading 3-0, McMillian intercepted a Lance pass that bounced off the hands of KeAndre Lambert-Smith and ran untouched down the left sideline into the end zone with 3:39 left in the first quarter.

“It’s crazy,’’ McMillian said. “We actually ran that play in practice and I messed it up. I had to redo it. (Defensive coordinator Vance Joseph) gave me the coaching point on it. … It’s a great feeling.”

Payton had emphasized heading into the game that the Broncos needed to force more turnovers. The Broncos entered Sunday’s game with a minus-5 differential despite their gaudy record. But they had a plus-2 differential against the Chargers.

“Score on defense (and teams win) 88% (of the time),’’ Payton said. “In the last 25 years, there’s only been one Super Bowl winner … that finished minus (in turnovers in the postseason). … We talked about it starting (Sunday getting turnovers).”

On offense, though, Payton didn’t deny the Broncos have some things they need to improve upon.

“Am I ever happy?’’ he said. “No, but we shouldn’t be as coaches… Yes, we have to clean some things up, and we will. We’ll be ready.”

The Broncos will be off until they have practices Friday and Saturday. Then they will be off again Sunday before taking the field Monday in preparation for their divisional playoff. The soonest the Broncos can know their foe will be Sunday night and they might not find out until Monday night.

Until they are back at practice and looking at what they have to clean up, the Broncos can look back at what they have done so far this season.

“It’s a big accomplishment for us, especially for this organization knowing what we’ve been through (and) how long it took us to get to this spot,’’ said cornerback Pat Surtain II, a five-year veteran whose Broncos had a losing record in his first three seasons.

“Winning 14 games in a season is incredible,’’ said tight end Adam Trautman.

If the Broncos win some games in the playoffs, expect celebrations to be really ramped up.
