Three weeks ago, Seattle won this divisional match-up 19-9 in a bit of a grindy, lacklustre affair.
Since then, Arizona have lost Hollywood Brown to injury but got DeAndre Hopkins back after his suspension. It's probably a bit of an upgrade overall, but having only one main receiver threat is limiting and makes it easier for defenses to gain the upper hand.
The Seahawks wide receiver pairing of Lockett and Metcalf is almost certainly better than Hopkins and TE Zach Ertz, and Kenneth Walker is probably posing more of a run threat than the Cardinals can offer at the moment even with Kyler's little legs pumping.
On form, Arizona are an okay team who haven't been able to build any real momentum, while Seattle have shown more consistency and there is a buzz about the place.
I don't see any real reason to think that Seattle aren't just a slightly better team, so them being c.11/10 underdogs here looks generous.
Selection is Seattle to win, with the 2-2 predictor (meh) having this assessed as Seattle Seahawks 30-20 Arizona Cardinals.
