Thursday Night Football Same Game Parlay: Seahawks vs. Cardinals – It’s an NFC West divisional battle on Thursday Night Football.Â
In the blink of an eye, we’re on to Week 4 of the NFL season!
Thursday Night Football presents a crucial NFC West showdown: the Seattle Seahawks (2-1) travel to face the Arizona Cardinals (2-1) in an early-season matchup that could mean huge momentum with a primetime win.
Both teams have shown early promise and some vulnerability, but recent developments tilt the edge toward Seattle. The Seahawks’ defense has allowed just 17, 17, and 13 points in their first three games, ranking 2nd in the NFL in points allowed. Meanwhile, Arizona not only lost to San Francisco in a nail-biter in Week 3, but also lost running back James Conner for the season due to an ankle injury. Trey Benson steps in, but that’s a major loss for an offense that was still looking to find its way.

Oddsmakers have set the spread at Seattle +1.5 (−110) and the total at 43.5. Given Seattle’s defensive strength, Arizona’s offense struggling, and the historical dominance of Seattle in this head-to-head matchup (7 straight wins, 8 out of last 9), there’s value in a parlay combining Seattle +1.5 with Under 43.5.
This ticket focuses on limiting scoring, controlling tempo, and capitalizing on Arizona’s offensive weaknesses. I will admit I’m a bit timid with Seattle coming off a blowout win and Arizona coming in off a last-second loss, but I think the Seahawks are a legit threat in the West.
Thursday Night Football Same Game Parlay: Seahawks vs. Cardinals
Leg 1: Seahawks +1.5 Spread
-
The Seahawks are slight underdogs despite their strong defensive metrics; their ability to keep games close, especially on short weeks, gives value to the +1.5.
- The Seahawks have been elite in pressuring the QB, and that spells trouble for Kyler Murray.
-
Head-to-head, Seattle has won the last seven meetings with Arizona, often preventing the Cardinals from pulling away. That trend plus Arizona’s injuries points to Seattle possibly covering or even winning outright.

Leg 2: Under 43.5 Total Points
-
With Arizona’s offensive firepower diminished (Conner out), the scoring upside drops. Meanwhile, Seattle’s defense has been one of the most dynamic in the NFL through three games, and defense always travels.
-
The 43.5 line is modest given both teams’ trends: the Seahawks have held opponents under 20; the Cardinals have not scored more than 20 in two of their three games. That set-up makes this under attractive, even in a primetime matchup.
| Leg | Pick | Odds / Line |
|---|---|---|
|   Leg 1 | Seahawks +1.5 | −110 |
| Leg 2 |  Under 43.5 Total Points |  −110 |
| Estimated Same Game Parlay Odds | Â +225 | |
Among the reasons the Seahawks saw Sam Darnold as a strong fit in Klint Kubiak’s offense, with all its designed rollouts, was his ability to throw accurately on the run — even while moving to his left.

This is a difficult game to call, as I really like both of these squads, and we were on both of them last week, and they both covered.
However, this Seahawks vs. Cardinals same game parlay is rooted in matchup strength, injury impacts, and defensive performance from the Seahawks. Seattle +1.5 provides a buffer in a game likely to be competitive but low-scoring. The Under 43.5 aligns with Seattle’s defensive dominance and Arizona’s diminished offensive toolkit without James Conner.
If Seattle controls the line of scrimmage and Arizona struggles to finish drives, both legs move toward cashing. While game swings and turnovers can disrupt things, this parlay offers a strong odds-to-risk ratio. If the Seahawks can win this game, it will be largely due to the defense and the under hits.
Take Seahawks +1.5 & Under 43.5 as your ticket. Best of luck!
