The 49ers and Seahawks square off on Sunday, Sept. 7, at Lumen Field, where the noise will be deafening and the stakes high. For Seattle, this game represents the dawn of a new era. It’s year two of Mike Macdonald’s tenure as head coach. It’s also year one of Sam Darnold’s tenure as the team’s starting quarterback. Opening day in Seattle is always intense, but the prospect of knocking off San Francisco would electrify a fanbase desperate for momentum. After all, it’s been four long years since the Seahawks last beat the Niners at home.

The 49ers, meanwhile, enter 2025 with high expectations after retooling both their offense and defense. Kyle Shanahan’s squad remains loaded with stars like Brock Purdy, Christian McCaffrey, Brandon Aiyuk, and George Kittle. With Robert Saleh returning as defensive coordinator, San Francisco is determined to set the tone early in what many believe is a Super Bowl-or-bust campaign. Seattle wants to show it’s ready to compete for the division crown. San Francisco wants to show the gap between the two teams is as wide as ever.

Here we will look at and discuss some bold predictions for the game between the 49ers and the Seahawks in Week 1 of the 2025 NFL season.

A sloppy first half

Opening games are rarely clean. This one projects to follow that script. Both teams have undergone significant changes, particularly Seattle with a new offensive scheme and quarterback. Darnold has the tools to succeed. However, Week 1 against a fast, aggressive 49ers defense is a brutal way to begin. Don’t be surprised if missed throws, penalties, or turnovers define the first half.

For San Francisco, too, early jitters are possible. With so many stars coming back from injury-shortened 2024 seasons, rhythm might take time to establish. Expect a close, potentially messy first half. Field goals and stalled drives will dominate the scoreboard. As the game progresses, though, the difference in talent and continuity should begin to emerge.

Jaxon Smith-Njigba has 70+ yards and a touchdown

If there’s a bright spot for Seattle, it’s the ascension of Jaxon Smith-Njigba. Entering his third season, the young wideout is poised for another leap. Yes, Darnold may struggle against Saleh’s blitz-heavy schemes. That said, Smith-Njigba’s crisp route running and ability to create yards after the catch will give the Seahawks some much-needed sparks.

The 49ers’ secondary has talent but can be vulnerable to shifty receivers who thrive in space. Smith-Njigba is exactly that type of playmaker. Look for him to log at least 70 receiving yards and find the end zone once. He can keep Seattle within striking distance. If the Seahawks are going to have a chance at pulling off the upset, Smith-Njigba will have to deliver a big performance.

Shanahan’s offense shines

Brock Purdy is still one of the NFL’s best feel-good stories, but with his rise comes responsibility. He now leads one of the league’s most talented offenses, ranked by pundits as second only to Baltimore. Even with Christian McCaffrey, Brandon Aiyuk, George Kittle, and Trent Williams all missing significant time last season, San Francisco still managed a top-five finish.

Now fully healthy, Kyle Shanahan has his entire arsenal at his disposal. Expect McCaffrey to shred Seattle’s run defense and Kittle to exploit mismatches against linebackers. The Seahawks’ offense remains a work in progress, while the 49ers’ unit runs like a finely tuned machine. Once Shanahan’s group hits its rhythm, this matchup could get lopsided in a hurry.

Seahawks’ rally falls short as Niners win

Seattle won’t roll over, though. With a packed house and the energy of a season opener, the Seahawks will fight to the end. Darnold will make a few gutsy throws, and Smith-Njigba will shine. Still, Robert Saleh’s return to San Francisco could not come at a better time. His attacking defense will overwhelm Seattle’s shaky offensive line. They will produce sacks and turnovers that swing the momentum firmly to the Niners.

In the end, the Seahawks’ rally will fall short. The 49ers simply have too much firepower and too much experience. Expect San Francisco to pull away late, winning by double digits—something like 27-16. It will be another frustrating night for Seattle fans, but for San Francisco, it will be exactly the kind of statement win they need to launch their season.

Final thoughts

The Seahawks want to prove they can hang with the 49ers in the NFC West race. The 49ers want to show they’re still the division’s dominant force. Indications point to a sloppy opening half, a breakout showing from Smith-Njigba, and an offensive showcase from Shanahan’s crew. Ultimately, though, San Francisco’s depth, talent, and coaching edge will decide the outcome.

The noise at Lumen Field will be loud. The fight will be real. But when the dust settles, the 49ers’ championship aspirations will look intact. Meanwhile, the Seahawks will still be searching for answers.
