Arizona Cardinals vs Seattle Seahawks prediction: Moneyline value review

Seattle host Arizona in Week 9, but this is not a straightforward favorite selection. The Seahawks are 4-4 and Cardinals 3-5. Seattle won 31-7 in Arizona earlier in the season, yet injuries have changed the rematch considerably: Drew Lock replaces Sam Darnold at quarterback, while Arizona has turned to Gardner Minshew.

Independent football assessment

Seattle's defense has allowed 19.9 points per game compared with Arizona's 29.8. That ten-point defensive gap supports a Seattle preference, even with the home offense weakened by the loss of starting quarterback and several linemen. Arizona scored 33 against Dallas in a comeback, which illustrates how quickly the matchup could change if Minshew protects the ball and finds explosive plays.

A cautious illustrative projection is Seattle 24-17 Arizona, a seven-point home margin and 41 combined points. This is a qualitative scenario, not a calibrated score model.

Market comparison

The available moneyline shows Seattle at 1.25 and Arizona at 4.40. The main spread is Seattle -8.5 and the total 39.5. A seven-point projected margin would fall short of a Seattle -8.5 cover, yet a single projected score cannot establish true cover probability or fair value. Nor can the market price alone confirm an edge. Without an independently executed win and score distribution model, no positive expected value is claimed.

Injury and execution risks

Seattle will be without Darnold, Charles Cross and Quenton Nelson, among several others. Arizona has offensive line absences, and Minshew starts in place of the previous quarterback. Both offensive lines could affect protection, turnovers and scoring opportunities. Late availability and game-day conditions may alter the outlook.

Final verdict

Predicted winner: Seattle Seahawks
Illustrative win chances: Arizona 30% / Seattle 70%
Projected score: Arizona 17-24 Seattle
Main market pick: Seattle moneyline
Value judgment: NO BET on an independently verified edge.

Seattle's defensive advantage is the strongest reason to favor the home side, while the missing starters prevent a high-confidence recommendation.
