JACKSONVILLE – It started rough, and never got better.

It also started methodically for the visitors and stayed that way, too – and none of it was remotely good for the Jaguars.

With rookie quarterback Trevor Lawrence and the Jaguars' offense struggling, and with their defense making key mistakes early, the San Francisco 49ers were efficient and physical Sunday. The combination was more than enough for the 49ers to pull easily away for a 30-10 victory in front of 60,268 at TIAA Bank Field.

"We have to put better stuff out there on the field; that was bad today," Lawrence said.

Lawrence, the No. 1 overall selection in the 2021 NFL Draft, completed 16 of 25 passes for 158 yards and no touchdowns with no interceptions. The Jaguars had 83 total yards at halftime, by which time San Francisco led 20-3. The Jaguars finished with 200 yards of offense.

Head Coach Urban Meyer called it "a very poor display of football in so many areas."

"I was extremely disappointed with everything about today, but you keep going," Meyer said. "You keep working. There are times we have played excellent football. Today wasn't one of those days."

The Jaguars (2-8) lost a second consecutive game after winning two of three games around an October 24 bye.

"There's not much left to say," Lawrence said. "We just have to keep going. The season's not going to get canceled. We have seven more games left. We have a lot of ball left. We just have to get better every week. I'm not going sit up here and say all of the positive things that came out of it.

"There's not much out of today. We got our butt kicked. It didn't look good all the way around."

Sunday's tone was set on the 49ers' first possession, and it never changed.

The 49ers (5-5) moved methodically on the drive, using 20 plays to march 87 yards to the Jaguars 2 – with kicker Robbie Gould's 20-yard field goal giving them a 3-0 lead. San Francisco held possession for 13:05 on the drive and scored on its first five possessions en route to a 27-3 lead midway through the third quarter. They didn't punt until 2:51 remained in the third quarter.

San Francisco quarterback Jimmy Garoppolo completed of 16 of 22 passes for 176 yards and two touchdowns with no interceptions. The 49ers finished with 333 total yards and 25 first downs.

"We lost bad. It's embarrassing, and we should feel (bad) -- because no group played special," Jaguars defensive end/linebacker Josh Allen said.

The Jaguars, who have scored 43 points in their last four games, have scored just two meaningful touchdowns during that span. They haven't scored a touchdown trailing by less than double digits since a victory over Miami on October 17.

"We have to be better," Lawrence said. "We were starting to do that as the year went on and the past few games offensively haven't been great. We have to find that again."

Their lone touchdown Sunday came with 3:04 remaining, when running back James Robinson's one-yard touchdown run cut the 49ers' lead to 30-10.

"There's not a magic pill of, 'This is what we need to do to fix it,''' Lawrence said. "We all just have to take ownership and be better. Until we do that, it's going to be the same thing. We have to keep going back to work. It will come. This is definitely disappointing."

The Jaguars were penalized eight times for 56 yards Sunday, with four first-half penalties for 31 yards on the defense leading to 10 San Francisco points. The Jaguars registered two sacks – one each by linebacker Damien Wilson and defensive lineman Roy Robertson-Harris – and had no takeaways. They have a league-low five takeaways for the season.

"I'm mad," Allen said. "We've got to move on. We've got to learn from our mistakes and not make the same mistake because you know they carry on. So learn from these mistakes, grow from it, get better, and play great football."

Step by step:

• The 49ers took a 3-0 lead on Gould's 20-yard field goal; a holding penalty on Jaguars safety Rayshawn Jenkins and a later offsides penalty on defensive end Dawuane Smoot converted third downs for the 49ers, who also converted 3rd-and-12 from the Jaguars 47 with a 13-yard pass from Garoppolo to wide receiver Brandon Aiyuk.
• San Francisco extended the lead to 10-0 with a 25-yard run by wide receiver Deebo Samuel with 11:24 remaining in the second quarter; Garoppolo opened the drive with a 34-yard pass to Aiyuk for a first down at the Jaguars 46 to start the second quarter. The 49ers had outgained the Jaguars 156-5 after Samuel's touchdown. Jaguars wide receiver Laviska Shenault Jr. fumbled after a six-yard reception on the first play of the ensuing possession, with 49ers linebacker Fred Warner recovering at the Jaguars 35. Garoppolo finished the next drive with a six-yard pass to Aiyuk for a 17-0 lead with 8:25 remaining in the half; Jenkins gave the 49ers a first down with an unsportsmanlike conduct penalty and was ejected for throwing a punch, with linebacker K’Lavon Chaisson committing a roughing-the-passer penalty that gave the 49ers 1st-and-goal on the 6. A 30-yard field goal by Jaguars kicker Matthew Wright with 1:53 remaining in the second quarter cut the 49ers lead to 17-3. Gould's 48-yard field goal on the final play of the half pushed the lead back to 17 points, 20-3.
• The 49ers took a 27-3 lead with Garoppolo's one-yard touchdown pass to tight end George Kittle, capping a 77-yard drive on their first possession of the second half; a key play was a 21-yard end run by Samuel to the Jaguars 3, and the 49ers at that point had scored on all five possessions.
• A 45-yard field goal by Gould with 5:33 remaining pushed the 49ers' lead to 30-3. Robinson's one-yard touchdown cut the lead to twenty with 3:03 remaining.
