Jimmy Garoppolo throws it like it’s 2017

In 2017, quarterback Jimmy Garoppolo made his debut for the San Francisco 49ers when starter CJ Beathard was injured in a game against the Seahawks at Levi’s Stadium.

Garoppolo’s second pass was a touchdown.

On Sunday, Garoppolo made his 2022 debut when starter Trey Lance was injured in a game against the Seahawks at Levi’s Stadium.

Garoppolo’s fourth pass was a touchdown.

Interestingly, Garoppolo said the 49ers’ 27-7 victory on Sunday had some 2017 vibes. But not because of the opponent, the stadium, the injury that prompted his insertion or his initial success.

Rather, it was because Garoppolo was shooting regularly from the field, which was similar, he said, to five years ago when he took over a team 1-10 and had no a full understanding of the playbook. Garoppolo said he was “ecstatic” to be back in let-it-rip mode.

“It was just nice,” Garoppolo said. “We were talking earlier, it felt a bit like 2017, where you just throw, make games. That’s what I like to do. It’s different from what we usually do here, but sometimes it has to be done.

His game manager stat sheet (13 for 21, 154 yards, TD) didn’t suggest Garoppolo was throwing deep on every other attempt. Three of his goals did not go beyond the line of scrimmage. He didn’t have a completion that traveled more than 16 yards down. The average depth of his achievements: 5.7 yards.

However, Garoppolo constantly attacked on the pitch. He had passes that traveled 16, 18, 18 and 20 yards beyond the line of scrimmage, resulting in three pass interference penalties and an illegal contact violation. Those penalties resulted in four first downs and 57 yards, and two were part of touchdowns.

Garoppolo also had a pass in the second quarter, 33 yards down, which wide receiver Brandon Aiyuk dropped along the left sideline. On the next play, 4-and-9 from Seattle’s 39-yard line, Garoppolo targeted speedy rookie Danny Gray in the end zone on an incomplete.

As Garoppolo mentioned, it was different from what head coach Kyle Shanahan has asked him to do in recent seasons. Of course, it’s worth noting that Garoppolo inherited a game plan suited to Lance on Sunday, who has a bigger arm.

Fullback Kyle Juszczyk referenced the Lance-focused plan – and Garoppolo’s shooting – when asked if the offense would change now with Lance out for the season with a broken ankle.

“I would say yes, but Jimmy kept the ball in read zone today and threw two balls, or maybe three,” Juszczyk said. “Jimmy executed the game plan we had for today. (But) some things could change.

Garoppolo made his feelings clear. He hopes some things from Sunday will stay the same.

Other observations from the win over the Seahawks:

• About this Garoppolo-led zone reading: Um, why did Shanahan call that?

Already down from a starting QB and leading 20-7 with two minutes to go, Garoppolo headed a zone guard on the 3rd and the goal of the 2 in which he took a shot at the end of a gain of 1 meter. When asked about his decision, Shanahan said Garoppolo should have moved to running back Jeff Wilson because defensive end Darrell Taylor stayed home and stopped Garoppolo from running on the outside.

“We need to read the D-end a little better and work on that, so when the D-end takes the quarterback, you put him back,” Shanahan said. “But it’s a very normal game, in all of football, at all levels, for everyone. I’m surprised you haven’t seen some of the quarterback running areas read about us.

Shanahan obviously won’t remove zone reads from the playbook, even with seventh-round rookie pick Brock Purdy now serving as backup QB. Shanahan certainly won’t stop calling QB sneaks for Garoppolo after going 2-2 on Sunday. Garoppolo converted 26 of 27 sneaks into 3rd or 4th and 1 of his career.

“Actually, a stepping back game is riskier than a sneaky quarterback, so those are the things that really confuse me,” Shanahan said. “I see guys getting killed in the pocket on dropbacks. And I’ve never seen a quarterback get hurt sneaking around before.

Shanahan has often appeared exasperated with questions about Lance’s use as a runner, increasing his risk of injury. On Monday, a reporter joked that it looked like Shanahan wanted to ask another question on the matter.

“I’m good with it,” Shanahan said. “In fact, the more the better, so I can help educate.”

• DeMeco Ryans defensive coordinator didn’t bring much extra pressure, but his blitzes were largely effective.

The Seahawks’ first possession ended when Ryan sent linebackers Fred Warner and Dre Greenlaw to blitz 3rd-and-5 from Seattle’s 41-yard line. Sending six rushers meant cornerback Emmanuel Moseley was one-on-one against DK Metcalf, but Moseley had the Pro Bowl wide receiver covered when he was targeted on an incomplete tilt.

In the second quarter, Ryans brought the heat after the Seahawks’ second-longest gain of the game, a 17-yard reception by wide Tyler Lockett.

Strong safety Talanoa Hufanga blitzed down the right side, forcing Geno Smith to throw a rushing pass to tight end Will Dissley, who was dropped by Greenlaw for a 2-yard loss.

• Why was tight end Ross Dwelley so open on his 38-yard touchdown from Garoppolo in the second quarter?

It is difficult to attribute responsibility for the blown cover. But it didn’t help that linebackers Cody Barton and Jordyn Brooks both broke to wide receiver Deebo Samuel as Dwelley passed them in the open.

The game was a prime example of how an All-Pro player can make an impact without doing much. Samuel got in motion before the snap and was 7 yards behind the line of scrimmage, near the left sideline, as Garoppolo shot down.

• Reserve defensive tackle Hassan Ridgeway had seven shots, had no stats and had one of the biggest plays of the game.

Ridgeway had a big assist on free safety Tashaun Gipson’s interception in the second quarter because he rushed center Austin Blythe in Cupertino. Smith’s through pass was off target because his right arm hit Blythe’s helmet after the cross was driven into his lap.

• Rookie running back Ty Davis-Price finished the game despite a sprained ankle that will sideline him for several weeks.

Davis-Price was not visibly hampered, but his injury could have reflected on the stat sheet. The third-round pick had 24 yards on his first two carries — and 9 yards on his last 12.
