49ers Look to Overcome Seahawks Defense in Key NFC West Clash

San Francisco heads to Seattle with first place in the NFC West on the line. The 49ers have struggled against Mike Macdonald's defenses, including a playoff blowout and several low-scoring performances. The story examines whether Kyle Shanahan and Brock Purdy can finally solve that problem.
San Francisco enters Seattle with NFC West first place at stake. A win could give the 49ers a multiple-game division lead and tiebreakers over both Los Angeles and Seattle. Last season, Seattle's defense twice stifled San Francisco in three weeks, capped by a 41-6 playoff rout.
The history with Mike Macdonald is stark. In 2023, while directing Baltimore's defense, he watched Brock Purdy throw four picks in a 33-19 Christmas loss. San Francisco won 36-24 in 2024, but since then has scored at most 17 points in four meetings, losing three and failing to reach the end zone in the past two.
A 49ers win could shift the NFC West race and playoff seeding, affecting players, coaches, and fans in San Francisco and Seattle. It may shape MVP talk around Purdy and perceptions of Shanahan's offense. For media and local businesses, a high-stakes divisional game could draw attention and spending, though impact likely remains limited to sports audiences.
