49ers Go 5-0 in Instant Classic; Edge Seahawks in NFC West Thriller...

San Francisco's perfect record puts them in sole control of the NFC West division race after a close win over Seattle. The 49ers have built their undefeated start through defense and a ground-heavy offense led by running back Christian McCaffrey, positioning them as one of the conference's top threats heading into the season's middle stretch. The Seahawks remain competitive in a division where multiple teams have realistic playoff hopes, but the 49ers' ability to win tight games gives them a significant edge in what's shaping up as a hard-fought divisional battle.
