In a commanding performance, the Seattle Seahawks defeated the Arizona Cardinals 16-6, showcasing a dominant defense led by Leonard Williams. The Seahawks held the Cardinals to under 290 total yards, with Williams recording 2.5 sacks and safety Coby Bryant scoring on a 69-yard interception return.

Geno Smith threw for 254 yards and a touchdown, but his decision-making raised concerns. The Seahawks' defense, particularly against the run, excelled, limiting James Conner to just eight yards. Despite the win, the Seahawks continue to search for a consistent run game and better pass protection.
