JACKSONVILLE – This wasn't what Trevor Lawrence wanted. Or expected.

The Jaguars on Sunday struggled offensively in a 17-9 loss to the Kansas City Chiefs at EverBank Field. It was a performance that reminded Lawrence of difficult times past – and that had the third-year quarterback pointed in his post-game analysis.

It was unacceptable, frustrating and more.

"It's kind of embarrassing," he said.

Lawrence, like Head Coach Doug Pederson, spoke extensively Sunday of a lack of execution by an offense that failed to score a touchdown for the first time since a 13-6 Week 5 loss to the Houston Texans last season.

"It's a similar feeling, honestly," Lawrence said.

Lawrence on Sunday completed 22 of 41 passes 216 yards and no touchdowns with no interceptions. The offense scored six points on five first-half possessions past midfield and finished the game with six points on three possessions inside the Chiefs 20.

"We got in the red zone, you have to score six points against that team; it's that simple," Jaguars tight end Evan Engram said. "We know we could be a lot better than that. It's just that simple. We have to execute when the plays matter. That's it."

Wide receiver Christian Kirk attributed the Jaguars' offense Sunday to "a lot of self-inflicted errors," calling the red zone issues a matter of "execution."

"It was hot, it was a long game, but we can't fall back on that," he said. "We're going to have another opportunity next week where it's going to be hot and we're going to have a divisional opponent [the Houston Texans at home]. We need to be better. I think it's all pre-snap of just locking into what your job is and doing that at the highest level. No matter how tired or how hurt you are, you've got to do it. And so that's what we're going to definitely focus on, is just selling out on each individual play.

"Obviously, that's a great football team and a great defense, so we tip our caps to them. But you look at it after, and there are so many opportunities that we missed. Collectively as a group, the guys that needed to make plays, there were times that the plays weren't made.

"It just caught up with us. I think that's what the hardest part is about this right now."

Engram emphasized the need for improvement moving forward from a Jaguars offense that ranked in the Top 10 in points and yards last season – and that entered the season with high expectations.

"We have to sit on this," Engram said. "We have to look at this tomorrow and take accountability for our play, the things that we left out there: Everybody; myself, the rest of the unit, coaches, players - everybody. We have to really breakdown this tape and be real critical of ourselves."

Lawrence called the offense "really sloppy." He also while he was not concerned about the Jaguars' offense after two games, "it's something we have to fix."

"It is an issue," he said. "We scored a lot of points last week [in a 31-17 victory over the Indianapolis Colts], but I don't think we played to our standard and how good we can play – and this week, not even close. Every play, every series, there's something we all can do better. It's definitely an issue. We have to all look in the mirror, be accountable and be critical of ourselves. It's all of us.

"Guys talked about after the game: There are plays we all missed on different series, different plays, whatever it is. We have to make those plays. That's what the good and great teams do.

"I'm not concerned, but we have to do it."

QUOTABLE

• Kirk: "We have a lot of pros in this locker room. Pros move on. It hurts right now, you digest the feelings today and then once tomorrow morning comes around, look at the film, be hard on yourself critically and then it's over with. You move on. This is Week 2 of a 17-week season and we're still very early on in writing our story. We're looking forward to doing that. It hurts now, but we're going to move on, and I believe this team will be ready to go next week."

QUOTABLE

• Linebacker Foye Oluokun: "It's a long season. We were fighting, that's what you have to take away from this game. We fight no matter who we play, all the way until the end."
