'Football 301' on 49ers vs. Seahawks: Brock Purdy and his offensive machine face their biggest test

The San Francisco 49ers enter Sunday’s NFC West showdown against the Seattle Seahawks as the league’s most dominant offensive unit, but their undefeated season faces its sternest test yet. Brock Purdy has thrived with a record-setting lack of sacks—none all season—while Kyle Shanahan’s play-calling has turned the Niners into a statistical juggernaut, though their reliance on George Kittle and Christian McCaffrey leaves them vulnerable when Seattle’s stifling defense, ranked third in stopping the run, steps up.

The Seahawks’ front seven, particularly adept at disrupting zone schemes, could finally break San Francisco’s sackless streak, while their elite pass defense has allowed just eight explosive throws all year—a stark contrast to the league average of 18. With Kittle and Shanahan’s creative schemes under pressure, this clash in Seattle may force the 49ers to adapt or risk their first loss of the season against a defense that thrives on disciplined execution and physicality.
