LONDON – His approach this season is simple and measured.

"For me, it's a week-to-week basis," Josh Allen said.

It's working. Big-time.

Allen, the Jaguars' fifth-year outside linebacker, continued the strongest start of his NFL career to date Sunday. He registered three sacks, including a game-clinching sack/fumble, in a 23-7 victory over the Atlanta Falcons at Wembley Stadium.

"He was in a great head space before the game, this whole week," Jaguars Head Coach Doug Pederson said. "It was an outstanding performance, and obviously the big one there at the end. It's what he's capable of doing."

Pederson called Allen one of many players key to the Jaguars' success – a group that includes quarterback Trevor Lawrence and wide receivers Christian Kirk, Calvin and Zay Jones among many others.

"He's in that conversation," Pederson said. "Those are the guys that need to step up and make plays, and he did a great job for us today. It's something that he can be proud of and we can work on that."

Allen, the No. 7 overall selection in the 2019 NFL Draft, registered a career-high sacks in a 31-21 Week 1 victory over the Indianapolis Colts. He started toward matching that early Sunday with a pair of first-half sacks on Falcons quarterback Desmond Ridder.

Those were part of a strong defensive performance in which the Jaguars registered four sacks and three turnovers, with Allen's sack/fumble recovered by defensive tackle Angelo Blackson with 1:33 remaining ending the Falcons' final drive.

"It was definitely progression," Allen said. "It was a heck of a way to fight, heck of a way for guys to make plays when their number was called, and for my performance, I couldn't do a lot of it without the guys in front of me."

Allen said was disappointed with his performance in a 37-17 loss to the Houston Texans last week and that he felt "I personally let the team down."

"This week was just, 'Get back on track,' and got back on track," Allen said, adding: "For me, it's just day-to-day. I try not to become a robot and say, 'I have to do this; I have to do this. If I don't do this, it's not going to happen.'

"I'm really in the moment and just handling my business. For me, this is strictly business. I'm about my business, and I'm ready to win games. I want to be the guy for the defense that we can count on."

Allen, who entered the season with 27.5 career sacks, now has six through four games this season.

"I don't know what he's eating, I don't know what he's drinking," Jaguars cornerback Darious Williams said. "He's doing something because he's going crazy. We need that. That helps the whole defense. That helps us."

NOTABLE

• As wide receiver Christian Kirk saw it, Sunday was a positive step for the Jaguars' offense – but only a step. The Jaguars produced 306 yards and a touchdown Sunday, producing two critical field-goal drives in the second half to secure the victory after the Falcons cut a 17-0 halftime lead to 17-7 early in the third quarter.
• "I definitely think it's a step in the right direction, and it started early on this week," Kirk said. "We kind of talked about it, just our sense of urgency and our execution and discipline throughout the week of practice. You kind of felt that we were going to get back on track with where we needed to be and just to go out there and be ourselves, and I thought we did that. I still think we have a long way to go to be a really good offense. There's still some mistakes and some things that we didn't do as well today, but we were able to make enough plays to go out there and get enough points to get a win."

QUOTABLE

• Jaguars quarterback Trevor Lawrence: "I think we had that confidence about us. I don't want to say loose and relaxed. I think that is important, but we were very intense and focused on the details. I think we just let it loose today as far as just going and playing. We didn't really worry about doing anything wrong or making mistakes. We just went and played. I think more the intensity and stuff during the week, I think that helped us coming into today, more so than tightening up on Sunday."
