Seahawks vs Cardinals Prop Bet Picks 9-20-26

NFL Score Prop Model: Seahawks vs Cardinals

Market-blind score projection: Cardinals 21 – Seahawks 16

Projected total: 37
Projected margin: Arizona by 5
Confidence: Moderate. Seattle’s quarterback change from Sam Darnold to Drew Lock, plus starting RG Anthony Bradford and safety Ty Okada being out, materially lowers the Seahawks’ offensive consistency and raises Arizona’s chance to sustain drives. Arizona has its own OL/DL availability concerns, so this is a lower-scoring, variance-heavy game rather than a Cardinals offensive breakout.

This Stage 1 score does not use the listed Seattle -3.5, 40.5 total, moneyline, implied team totals, or player-prop lines to create the forecast. Prop lines enter only after the score/projection lock.

Stage 1: Seahawks vs Cardinals Score Projection

Key inputs

• Seattle QB downgrade: Sam Darnold is out with a glute injury. Drew Lock makes his first Seahawks start since 2023; Jalen Milroe is the backup. Lock threw for 187 yards and one TD after replacing Darnold in Week 1, but the model downgrades Seattle’s passing efficiency over a full start.
• Seattle line/secondary absences: Starting RG Anthony Bradford and S Ty Okada are out. S Nick Emmanwori is questionable and could also miss, while Christian Haynes may make his first NFL start at right guard.
• Arizona availability: CB Garrett Williams is out; two starting guards, Isaac Seumalo and Isaiah Adams, plus DL Roy Lopez and Andrew Billings, are questionable. The Cardinals made no practice-squad elevations, suggesting at least some questionable linemen should play, but uncertainty remains.
• Arizona offense: Jacoby Brissett completed 27 of 37 passes for 277 yards in Week 1, while Trey McBride posted 9 catches, 95 yards, and a TD. The model regresses those raw outputs but retains McBride’s high target-share role.
• Venue: State Farm Stadium eliminates major weather effects.

Why Arizona projects ahead

1. The full-game QB edge is now Arizona’s.
   Brissett’s steady short/intermediate profile projects better than Lock’s full-game efficiency behind a depleted Seattle interior line.
2. Seattle’s pass game becomes more concentrated and easier to defend.
   Jaxon Smith-Njigba remains the primary option, but Lock’s lower expected attempt efficiency and the absent right guard reduce the probability of Seattle generating a high passing total.
3. Trey McBride’s middle-of-field role is especially favorable.
   Seattle is without Okada and may also lack Emmanwori. That makes a short/intermediate TE target more stable than a high-variance outside WR projection.
4. Low total does not mean zero prop volume.
   The model sees Arizona winning with efficient short passing, controlled rushing, and a defensive advantage—not a game that produces large downfield-stat ceilings.

Score Construction

Seahawks vs Cardinals Locked Game Script

First half:
Arizona moves the ball through Brissett’s short/intermediate game,
with Trey McBride as the volume hub. Seattle leans on its run game and
Jaxon Smith-Njigba but has trouble sustaining an efficient passing attack.

Second half:
Arizona protects a one-score lead through short throws and rushing volume.
Seattle asks Drew Lock to throw more, but the QB/guard downgrade creates
a lower yards-per-attempt ceiling.

Final state:
Cardinals 21 - Seahawks 16.

Stage 2: Distribution and Prop Comparison

The player distribution is locked above. The table below uses only post-lock market references.

A current published market reference lists Jacoby Brissett over 220.5 passing yards as a featured prop. I did not locate reliable line-level public references for Lock, McBride, JSN, or Harrison in the retrieved results, so confirm live numbers at DraftKings, FanDuel, bet365, Bovada, or BetOnline before betting.

Best Model-Derived Thresholds

1. Drew Lock Under Passing Yards
   Distribution:
   P10 / P50 / P90: 138 / 188 / 252
   Standard deviation: 43
   Example line: Under 209.5
   Model probability: 68.5%
   Fair odds: -217
   Playable to: -175 or better
   Confidence: B+
   Correlation: Darnold is out; Seattle's RG is out; Arizona leads and
   Lock is forced into less efficient late dropbacks.

2. Trey McBride Over 5.5 Receptions
   Distribution:
   P10 / P50 / P90: 4 / 6 / 10
   Standard deviation: 2.0
   Model probability: 59.6%
   Fair odds: -148
   Playable to: -125 or better
   Confidence: B
   Correlation: Arizona’s short-pass control script meets a depleted Seattle
   safety unit; McBride remains the target hub.

3. Trey McBride Over 61.5 Receiving Yards
   Distribution:
   P10 / P50 / P90: 41 / 69 / 108
   Standard deviation: 26
   Model probability: 59.1%
   Fair odds: -145
   Playable to: -115 or better
   Confidence: B
   Correlation: Same McBride target-concentration thesis; do not stake both
   at full size because receptions and yards are heavily correlated.

4. Jacoby Brissett Over 220.5 Passing Yards
   Distribution:
   P10 / P50 / P90: 178 / 229 / 294
   Standard deviation: 44
   Model probability: 57.4%
   Fair odds: -135
   Playable to: -115 or better
   Confidence: B-
   Correlation: Arizona controls the game through short/intermediate volume;
   Seattle’s secondary injuries support efficient passing.

5. Marvin Harrison Jr. Under 66.5 Receiving Yards
   Distribution:
   P10 / P50 / P90: 30 / 56 / 94
   Standard deviation: 25
   Model probability: 65.0%
   Fair odds: -186
   Playable to: -155 or better
   Confidence: B-
   Correlation: McBride absorbs the highest-percentage target volume,
   leaving Harrison reliant on fewer, more volatile intermediate/deep plays.
