Based on end-of-2023 data, Seattle holds a clear edge over Arizona, especially at home where they've been solid. The Seahawks have recent head-to-head dominance and a more stable roster, while Arizona is still in a rebuilding phase despite offensive upgrades. However, both teams have undergone coaching changes, and future roster shifts introduce uncertainty. Thus, while Seattle is the logical pick, the confidence is moderate given the two-year projection gap.

The Seattle Seahawks enter this matchup as clear favorites based on multiple analytical dimensions. Historically, the Seahawks dominate this division rival, winning 4 of the last 5 meetings and leading the all-time series 26-22-1. In 2023, Seattle finished strong under new head coach Mike Macdonald's defensive-oriented system, winning 3 of their final 5 games and improving team cohesion. The Cardinals, meanwhile, are rebuilding around Kyler Murray's post-ACL recovery and struggled significantly on defense (31st-ranked) in 2023, particularly away from home (2-7 record). The home/away splits heavily favor Seattle, who went 5-3 at Lumen Field compared to Arizona's dismal 2-7 road record. While the Cardinals added talent like Marvin Harrison Jr. in the 2024 draft, roster maturity and coaching stability favor the Seahawks. Expected score reflects Seattle's improved defensive play under Macdonald preventing high-scoring affairs.

By late 2026, the defensive culture established by head coach Mike Macdonald should be fully realized, providing a sophisticated scheme designed to contain mobile quarterbacks like Kyler Murray. While Arizona's offense is expected to be potent with the maturation of Marvin Harrison Jr., Seattle’s ability to generate pressure while maintaining discipline in the secondary remains a significant hurdle for the Cardinals. Furthermore, the Seahawks have shown greater consistency in divisional play and home-field performance. While Arizona is in a clear upward trajectory following their 2024 rebuilding efforts, the Seahawks' balanced approach—pairing a physical running game with a high-pressure defense—tends to wear down the Cardinals over four quarters. Expect a competitive game, but Seattle's defensive stability gives them the clear advantage.
