Game Overview

Saturday night will close with the third matchup between San Francisco and Seattle.

These teams met in Week 1 and then again in the regular-season finale.

The 49ers won in Seattle 17-13 in Week 1, while Seattle won 13-3 in San Francisco in Week 18.

This is the third time these two teams have met in the postseason, with each team winning once.

The Seahawks won a franchise record 14 games in 2025, making the postseason for the first time since 2022.

You can make the case that Seattle is the most complete team in the postseason, at least based on production to date.

On offense, the Seahawks have scored on 45.9% of their possessions (5th) and averaged 5.9 yards per play (6th).

Defensively, Seattle ranked second-best in the league (17.2 points per game) while allowing 4.6 yards per play (2nd).

San Francisco scored 20 total points in two games against Seattle.

When these teams last played in Week 18, San Francisco had a season-low 173 yards of offense.

The 49ers had a 31% success rate on offense that night, their lowest of the season.

The Seahawks also had one of the best special teams units in the league, ranking second in EPA.

They were tied for the league lead with 4 special teams touchdowns.

If both of these teams have a major fault on offense, it is that they both have had spurts of turning the ball over.

Seattle has turned the ball over on 14.1% of their possessions (31st) while San Francisco has turned the ball over on 13.3% (29th).

Those are the two highest rates among teams that made the postseason.

To their credit, the 49ers have allowed 26 total points to Seattle in the two matchups.

Going back to the last time these teams played in Week 18, Seattle outgained San Francisco 361 to 173 and punted just once.

But they allowed San Francisco to hang around by failing to capitalize on scoring opportunities, losing a possession on downs in the red zone and missing two field goals.

San Francisco had the ball at the Seattle six-yard line down 10 with 10:35 left in the game before an interception sealed their fate.

The 49ers have been battling all season through a flood of injuries.

The defense has not played well overall, but it has allowed 19 and 13 points in the past two games against Seattle and Philadelphia.

That is all you can ask for from the current state of this unit.

The 49ers lost another starter on defense last week in safety Ji’Ayir Brown, who suffered a hamstring injury.

To succeed against Seattle, you need to force them into obvious passing situations.

The Seahawks converted only 16.8% (17 of 101) of third-and-long situations (requiring 7 or more yards), which ranked second-to-last in the league.

On third and short situations (needing 3 or fewer yards), they converted 65.6% (40 of 61).

On offense, San Francisco suffered another blow with the Achilles injury to George Kittle.

Quarterback

Brock Purdy: Things were not super clean for Purdy last week.

He completed 18 of 31 passes (58.1%) for 262 yards with 2 touchdowns, also throwing 2 interceptions.

Even with the mistakes and his third-lowest completion percentage of the season, Purdy and this passing game found a way to generate enough big plays.

Purdy posted a season-high 14.6 yards per completion.

No passer in the league has had a higher rate of passes resulting in a first down or touchdown than Purdy (45.1%).

San Francisco will have to find a way to generate enough big plays here against a Seattle pass defense that has allowed a league-low 6.0 yards per pass attempt and 9.7 yards per completion.

Seattle allowed a league-low 6.3 yards per pass attempt without pressure this season.

When they did get pressure, they allowed 5.4 yards per pass attempt.

When these teams played in Week 18, Purdy threw for a season-low 4.7 yards per pass attempt.

He did complete 70.4% of his passes (19 of 27), but that was all Seattle gave him.

Purdy averaged 4.8 air yards per attempt in that matchup.

His previous season-low was 6.1 air yards per throw against Carolina, which was his only other game below 7.2.

In the first matchup between these teams in Week 1, he averaged 7.4 air yards per attempt.

Mike Macdonald‘s defense has thrown a wrench into this passing game.

In five career starts against a Macdonald-led defense, Purdy has a 45.7% success rate, below his career rate of 50.4%.

Purdy had a 37.5% success rate in the Week 18 matchup, which was his lowest of the season.

Purdy now has eight career games with a success rate below 40%, with two of those games coming against Macdonald.

In those five matchups, Purdy has averaged 7.2 yards per pass attempt with 6 touchdowns (4%) and 8 interceptions (5.3%) for a 79.7 rating.

Against everyone else, Purdy has averaged 8.5 yards per pass attempt with a 5.9% touchdown rate and a 2.6% interception rate (102.6 rating).

The 49ers have scored more than 19 points in one of those games.

If you are looking for some silver lining here, Purdy is 4-0 at Lumen Field.

Purdy has also been using his legs more.

He has rushed for 20 or more yards in four of his past five games, including 21 yards when these teams met in Week 18.

While Seattle has had an incredible pass defense this season, we did see Matthew Stafford throw for 457 yards, 9.3 yards per pass attempt, and 3 touchdowns in Seattle in Week 16.

Nobody expects those types of numbers from Purdy here, but the idea is that he and Kyle Shanahan can calibrate a game plan to create open targets like Sean McVay did after Stafford struggled for 4.6 yards per pass attempt in the first matchup between the Rams and Seahawks.

That, of course, is harder to do with the loss of Kittle.

Purdy did average more yards per pass attempt with Kittle off the field (8.1 Y/A) this season than with him (7.4 Y/A), but every other efficiency area drops off.

With Kittle on the field, Purdy has a 7.8% touchdown rate, 70.6% completion rate, and a 108.5 rating.

With Kittle off the field, Purdy has a 5.9% touchdown rate, 65.2% completion rate, and an 85.1 rating.

Sam Darnold: Darnold enters the postseason coming off career highs in completion rate (67.7%) and yards per pass attempt (8.5 Y/A).

He threw 25 touchdowns.

He did throw 14 interceptions, the most since his rookie season.

Reunited with Klint Kubiak, Darnold was under center for a career-high 53.9% of his snaps.

Darnold was one of the most effective passers using play action this season, averaging 11.4 yards per pass attempt (2nd) with a league-high 16.8 yards per completion on those attempts.

What is interesting about the Seattle approach is that either Seattle has been reining in Darnold as the season progressed, or opponents have done a better job at forcing this passing game to take more layups.

Through the opening 11 games of the season, Darnold led the NFL with 9.3 yards per pass attempt.

Over that period, he averaged 9.0 air yards per attempt (2nd) with 14.8% of his passes going 20 or more yards downfield (4th).

Since then, Darnold has averaged 7.1 yards per pass attempt (16th) with 5.9 air yards per attempt (30th) and a league-low 5% of his passes going 20 or more yards downfield.

He has thrown 27.4% of his passes 10 or more yards downfield over that stretch (27th) after a 39.3% rate prior (2nd).

Darnold has had his six lowest deep target passing rates of the season over the past six games.

I do believe there has been some defensive calibration, limiting the downfield stuff to Jaxon Smith-Njigba, but there may also be some internal preservation of “don’t lose us the game with this defense” at play.

Over that span, Darnold has seen his interception rate drop to 2.2% (16th) from 3.4% (31st) before that increased rate of shorter throws.

The two matchups between these teams tell the same story.

In Week 1, Darnold averaged 8.6 air yards per attempt with a 13% deep target rate.

In Week 18, he averaged 4.8 air yards per attempt with a 3.8% deep throw rate.

Darnold was 20 of 26 (76.9%) for 198 yards (7.6 Y/A) in that second outing, without a touchdown or interception.

This San Francisco pass defense has done a good job of not breaking, but there's still plenty of bend here.

The 49ers are 30th in the NFL in pressure rate (30.1%) and last in sack rate (3.3%).

Over the past 12 games, they have allowed a 67.4% completion rate (29th), but have tried to force opponents to throw underneath.

Over that span, they have allowed 6.9 yards per pass attempt (11th) and 10.3 yards per completion (5th).

Opponents have averaged 7.6 air yards per attempt over that stretch (10th).

When passers have taken shots downfield, however, they have been successful.

Over that same period, the 49ers have allowed 7 passing touchdowns on throws 20 or more yards downfield (30th) with a 14.3% touchdown rate (29th).
