The NFC West’s best early-season test in Week 5 comes with the San Francisco 49ers still unbeaten and the Seattle Seahawks trying to defend home field in a rematch from last season’s playoffs.
Seattle enters at 3-1 after a solid win over the Los Angeles Chargers, while San Francisco is 4-0 after taking down a strong Denver team in Week 4. The 49ers have gotten there with a long injury list on both sides of the ball, but Brock Purdy and Kyle Shanahan have kept the machine humming anyway. Purdy is the No. 2 choice for the league’s MVP, and San Francisco leads the NFL in EPA/Play and yards per play on offense.
The betting market has been bouncing this spread between 2.5 and 3, and it’s currently sitting at 2.5, with San Francisco available at plus money to cover. That line reflects a matchup that feels tight on paper, even with Seattle at home and the 49ers still being priced as an underdog for just the second time in 2026.
Seattle’s recent results have been uneven since Sam Darnold returned from a glute injury. The Seahawks are 1-1 with him back in the lineup, including a shocking road loss to Washington and then a win over the winless Chargers in Week 4. The offense has not taken a major step forward with Darnold under center, at least not over Drew Lock the last two weeks, even if the defense remains elite.
That’s part of why SI Betting’s Iain MacMillan is backing San Francisco in his Road to 272 picks. He called the 49ers the best team in the NFL through four weeks, pointing to their league-leading marks in DVOA, Net Yards per Play, EPA per Play, and success rate. He also noted that two of those wins came against the Dolphins and the Cardinals, and that the 49ers now have to deal with injury issues in a tough road game.
Still, MacMillan’s view is simple: if San Francisco is getting more than a field goal in a game he sees as a true coin flip, that’s the side worth taking.
The same logic makes the 49ers an appealing outright play here as well. They’ve already beaten the Los Angeles Rams and Arizona Cardinals in 2026, and their offense has been too productive - even with key pieces missing - to dismiss in a matchup like this.
For now, the call is straightforward: this looks like an upset spot, with San Francisco having a real chance to leave Seattle at 5-0.

Seahawks 49ers Clash May Come Down To These 3 Battles
The Seahawks and 49ers have spent the last four seasons turning their meetings into one of the NFC Wests most familiar grudges, with the rivalry carrying all the extra weight that comes from seeing each other so often, including in the playoffs. Seattle brings an offensive line that has been a real strength and a pass rush anchored by Leonard Williams and Derick Hall, while San Francisco still leans on the kind of centerpiece talent that can shape a game on either side of the ball.
What makes this latest matchup so intriguing is how much of it may come down to a few individual showdowns rather than broader trends. Fred Warner remains the kind of problem every opponent has to account for, and when the 49ers are at their best, Christian McCaffrey and George Kittle are usually part of the pressure they create. Seattle has reasons to feel good about its own fronts, but in a series this familiar, the margins tend to shrink fast and the key battles can decide everything. [Read more 🡒]
Seahawks Front Could Put Brock Purdy Back Under Real Pressure
The Seahawks head into their NFC West meeting with San Francisco carrying one of the more intriguing defensive matchups on the schedule. The 49ers have opened the season strongly, but Seattles front has been disruptive without needing to send extra heat, and that creates a different kind of problem for Brock Purdy than the usual blitz-heavy test. For a division game with this much familiarity, the line of scrimmage looms as the place where the whole thing could tilt.
Seattles pass rush has given opposing quarterbacks little room to breathe, and the challenge only gets sharper when the defense can get pressure with four and still keep the back end intact. George Kittle has already acknowledged the quality of the Seahawks defense, which only adds to the sense that Purdy will need to be sharp in a game where timing, protection and quick decisions may decide a lot. For Seattle, it is the kind of matchup that can validate the work it has put into building a front that can affect a game without chasing the quarterback all over the field. [Read more 🡒]
Seahawks Already Have A Few Early Standouts And One Frustrating Debate
The Seahawks have spent the first quarter of the 2026 season looking like a team with real playoff traction, and a lot of that momentum has come from the way different parts of the roster have filled in around the edges. Seattle is 3-1, Sam Darnold has missed two games, and Drew Lock has kept the offense on track in relief while Jaxon Smith-Njigba continues to stand out as one of the teams most reliable playmakers. On the other side of the ball, Emanuel Wilson, Rodney Thomas II and Nehemiah Pritchett have also surfaced as notable early contributors, giving the Seahawks some encouraging depth wins beyond the obvious names.
The harder part of the conversation, though, is separating the players who have forced their way into the spotlight from the ones who still feel stuck in neutral. Dante Fowler Jr. has been among the more frustrating underperformers, and Tory Horton has been the sort of player whose usage leaves you wondering how much more he could offer with a bigger role. Those kinds of early-season debates tend to matter for a team with postseason hopes, because Seattles margin for error may be shaped just as much by how it handles its frustrating cases as by the standouts who are already carrying their weight.
