Purdy is undefeated in Seattle with a 4-0 record, the best mark among quarterbacks with at least three starts there, highlighting the rarity of such a streak and boosting the 49ers' confidence heading into the divisional round.

This perfect Seattle record spans 2022 through 2025, with efficient performances, including solid passing totals and multiple touchdowns, and San Francisco winning each clash by an average margin of about 10.5 points.

San Francisco’s Week 18 loss to Seattle included injuries, notably Trent Williams, and his return is anticipated to strengthen the running game and Purdy’s pass protection.

Head coach Kyle Shanahan credits Purdy’s calm demeanor under pressure as a major factor behind his success in Seattle and the team’s belief in an upset possibility.

Despite Purdy’s track record, the 49ers enter as 7.5-point underdogs, with Seattle’s home-field advantage and recent form posing a significant challenge.

Purdy’s Seattle performances have featured high efficiency across games, contributing to consistent 49ers wins and reinforcing the narrative of his effectiveness in hostile environments.

If Purdy preserves his perfect Seattle record and San Francisco wins, the 49ers would advance to the NFC title game for the fifth time under Shanahan.

Overall, Purdy’s composure and accuracy in Seattle have reinforced a durable narrative about his ability to excel in tough venues.
