Written before the game and kept as published. Final: Seattle Seahawks 31, Arizona Cardinals 7 — the graded call is above.
Seattle Seahawks at Arizona Cardinals is a NFC West game, the first of two meetings, with the rematch in Week 9. The model has the Seahawks by 6 (66%) off a -4.4 to +4.1 rating gap. Division games carry weight the model does not price: head-to-head is the first tiebreaker in the NFC West, so a win here is worth more in January than the standings column shows.
The sharpest unit gap in the game runs one way: the Seahawks offense grades +0.6 (14th of 32) against a Cardinals defense at -3.8 (30th) — 4.4 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Cardinals offense (-0.6, 22nd) meets the Seahawks defense (+2.3, 2nd), a 2.9-point gap. Special teams adds to it: the Seahawks grade +1.1, 1st in the league, against -0.0 (29th) on the other side — close to a point of hidden margin.
On the standings side, NFC West games are the ones that decide the tiebreakers. Head-to-head record is the first tiebreaker between two teams in the same division, and division record is the next — so the value of this result is not just the win column. They meet again in Week 9, which makes a sweep the outcome with real leverage on the NFC West race.
Zoom out to the full season and the model projects the Cardinals at 6.0 wins (favored in 2 of 17) and the Seahawks at 10.1 (favored in 14) — 4.2 wins apart across the year. By win probability this is the 7th-hardest game on the Cardinals' schedule and the 12th-hardest on the Seahawks'.
Recent history, for context only: 48 regular-season meetings since 2002, 30-17 in the Seahawks' favour. They last met in 2025: Seahawks won 44-22 in November. Over their last 4 meetings the Cardinals are 0-4. It is not an input to the line — rosters turn over faster than series records do.
Does the model earn this number? In 448 of the 3266 walk-forward games it has been graded on (2013-2024, no market line used), it landed in the 65-70% range. Those favorites went 68%. The 66% on the Seahawks here sits in that same band, and the history backs it.
