Arizona’s opening win made this NFC West matchup more interesting in a hurry. The Cardinals controlled their game against the Chargers, while Seattle needed a fourth-quarter defensive takeover to escape its opener. Both teams are 1-0, but they got there in very different ways.
The central question is whether Arizona can sustain drives against a Seattle defense that just changed a game with takeaways. The Cardinals showed they can control possession and protect a lead in Week 1. Now they face a team with a much stronger recent track record and a market asking Seattle to win by more than a field goal.

Seattle’s defense is the matchup’s biggest test
Seattle trailed New England 10-0 in its opener and scored only three points through three quarters. The defense then intercepted Drake Maye three times in the fourth, helping the Seahawks rally for a 13-10 win. Drew Lock led two late scoring drives and connected with Jaxon Smith-Njigba for a 45-yard touchdown on fourth down, according to the AP.
That finish fits Seattle’s broader form. The Seahawks are 10-0 over their last 10 games, a run that stretches through the previous postseason and late last season, and they went 7-2-1 against the spread in that span. Six of those games stayed under their listed totals. That history doesn’t decide Sunday’s game, but it helps explain why a defense-led Seattle team is favored on the road after an uneven offensive opener.
Our projections give Seattle an edge in overall production, about 339 total yards to Arizona’s 314. The clearest difference is on the ground: roughly 117 projected rushing yards for the Seahawks and 87 for the Cardinals. If Seattle can create that separation without asking Lock to carry the offense, it has a straightforward route to controlling the matchup.
Arizona’s opener offers a real counterargument
The Cardinals were much sharper than their longer-term form suggested in a 26-14 road win over the Chargers. Arizona held the ball for 37 minutes, ran 72 plays and finished with a 393-268 advantage in total yardage. Jacoby Brissett threw for 277 yards and a touchdown as the Cardinals played from ahead throughout, as the AP detailed.
That performance matters because Arizona’s previous 10-game sample is otherwise rough: 1-9 overall and 2-8 against the spread. Week 1 doesn’t erase that record, but it showed a plausible route to staying competitive. Long possessions can limit Seattle’s opportunities, while the passing-yard prop market lists Brissett at 218.5 and Lock at 205.5.
The uncertainty is whether Arizona can repeat that efficiency against a defense that just produced three late takeaways. The Cardinals’ projected passing output is only narrowly higher than Seattle’s—about 227 yards to 222—so their path may depend more on avoiding negative plays and finishing drives than building a large yardage advantage.
Injuries could shape the line of scrimmage and secondary
The latest injury picture includes Seattle guard Anthony Bradford and safety Ty Okada being ruled out, while safety Nick Emmanwori is questionable. Arizona cornerback Garrett Williams is out. Cornerback Max Melton, safety Dadrion Taylor-Demerson, guards Isaac Seumalo and Isaiah Adams, and defensive tackles Andrew Billings and Roy Lopez are questionable in the NFL’s updated Week 2 report.
Those position groups are worth monitoring. Seattle is down a guard, while Arizona carries uncertainty along both lines and in the secondary. The designations establish who is out and who remains uncertain without telling us exactly how either team will adjust.

How the spread frames the matchup
Seattle -3.5 makes the pricing question simple: is the gap between these teams large enough to clear the extra half-point on the road? Seattle brings the stronger extended form, the more disruptive Week 1 defense and an advantage in our yardage projections. Arizona counters with home field and a convincing opener that looked much better than its late-2025 results.
The 40.5 total leaves room for another defense-influenced game. Four of Seattle’s last six games stayed under their listed totals, and Arizona’s opener also finished under. Those results provide context, but with both teams only one game into the new season, the more useful question is whether Arizona can reproduce the possession control it showed against the Chargers.
Seattle’s defensive ceiling is the strongest supported case in this matchup. Arizona’s Week 1 possession game and a spread sitting beyond a field goal provide the main counterweight. The factor that matters most is whether the Cardinals can stay on schedule; repeated long-yardage situations would let Seattle’s best unit dictate the afternoon.
