Seahawks at Cardinals Betting Prediction: Analyze Week 2 odds, injuries, matchups, trends, best bet, total, and projected score.

The Seahawks at Cardinals Betting Prediction for Week 2 of the 2026 NFL season leans toward the Arizona Cardinals +5.5 against Seattle. The Cardinals are coming off a 26-14 road win over the Los Angeles Chargers, while Seattle escaped its opener with a 13-10 comeback against New England.

The biggest factor is Seattle quarterback Sam Darnold being ruled out with a glute injury. Drew Lock will make the start after completing 16 of 22 passes for 187 yards and a touchdown in relief during Week 1.

Arizona also enters this matchup with a more productive offense after generating 393 total yards against the Chargers. Jacoby Brissett completed 27 of 37 passes for 277 yards and a touchdown without an interception, while Trey McBride caught nine passes for 95 yards and a score.

Best Bet: Arizona Cardinals +5.5

Secondary Bet: Under 41.5

Projected Score: Cardinals 23, Seahawks 20

Seahawks at Cardinals Betting Prediction: Week 2 Overview

The Seattle Seahawks and Arizona Cardinals both enter Week 2 with 1-0 records, but they arrived there in very different ways.

Seattle needed a fourth-quarter comeback to defeat New England 13-10. The Seahawks trailed for most of the game before their defense took control, forcing three interceptions in the fourth quarter. Drew Lock then helped engineer the offensive comeback after Darnold left the game.

Arizona produced the more complete offensive performance in Week 1. The Cardinals defeated the Chargers 26-14 in Los Angeles, with Brissett throwing for 277 yards and a touchdown. McBride was particularly productive, while Arizona also received major contributions from its defense and special teams.

That creates an interesting Week 2 betting matchup.

Seattle is currently listed around -5.5, while the game total is around 41.5 points. The line initially made Seattle a substantial road favorite despite Darnold’s injury, creating an important question about how much value remains with the Seahawks after the quarterback change.

The early statistical comparison favors Arizona on offensive production. Seattle gained 285 yards in Week 1, while Arizona generated 393. Seattle also converted only 18.2% of its third downs and failed to score a touchdown on its red-zone opportunities. Arizona converted 42.9% of its third downs and scored on 40% of its red-zone trips.

However, Seattle’s defense is the reason the Seahawks remain a significant road favorite.

---

Seattle Seahawks Week 1 Recap

Seattle’s 13-10 victory over New England was a defensive-driven win.

The Seahawks were unable to generate much offense early, and Darnold exited with his injury after taking a sack on the opening drive. Lock eventually settled in and completed 16 of 22 attempts for 187 yards and one touchdown.

The bigger story was Seattle’s defense.

The Seahawks intercepted Patriots quarterback Drake Maye three times in the fourth quarter. Seattle also recorded three sacks during the late comeback, turning a 10-0 deficit into a 13-10 victory.

That defense is already one of the biggest reasons Seattle entered Week 2 at the top of several power rankings. NFL.com’s Week 2 rankings placed the Seahawks No. 1 after the opening weekend.

But the offense remains a concern.

Seattle managed only 285 total yards and ran 48 offensive plays. The Seahawks also struggled on third down and did not convert a red-zone possession into a touchdown.

That makes the quarterback situation particularly important against Arizona.

---

Drew Lock Takes Over for Seattle

Darnold’s absence is the biggest development in this Seahawks at Cardinals Betting Prediction.

The Seahawks confirmed Wednesday that Darnold will miss the Week 2 matchup because of his glute injury. The team has described the injury as short term, but there is no firm return timetable. Lock will start, with Jalen Milroe serving as the backup.

Lock performed well enough after replacing Darnold in Week 1.

He completed 16 of 22 passes for 187 yards and a touchdown without throwing an interception. He also posted a 113.3 passer rating.

That performance gives Seattle reason to believe Lock can manage the offense.

Still, there is a difference between entering a game unexpectedly and preparing for a full week as the starter.

Lock should receive the majority of the first-team practice repetitions during the week, giving him additional preparation time.

The issue for Seattle is that Arizona’s defense should be able to focus more heavily on the passing game while respecting Seattle’s rushing attack.

The Seahawks will need to avoid turnovers and stay ahead of the chains.

---

Jaxon Smith-Njigba Could Be Seattle’s Offensive Key

If Seattle covers the spread, Jaxon Smith-Njigba could play a major role.

Smith-Njigba dominated Seattle’s receiving production in Week 1, catching eight passes for 122 yards and a touchdown. His 122 receiving yards accounted for a huge percentage of the Seahawks’ 200 passing yards.

Arizona allowed Justin Herbert to throw for 209 yards in Week 1.

That does not necessarily mean Lock will replicate Herbert’s production, but it does provide Seattle with a potential matchup advantage.

Smith-Njigba can help Lock by providing a reliable short and intermediate option.

That matters because Seattle does not need Lock to throw for 300 yards to win. The Seahawks need efficient drives, field position and protection for their defense.

If Smith-Njigba is able to consistently move the chains, Seattle can control possession and limit Arizona’s offensive opportunities.

---

Arizona Cardinals Week 1 Recap

Arizona entered the season as a significant underdog against the Chargers and responded with a 26-14 road victory.

The Cardinals moved the ball efficiently throughout the game, finishing with 393 total yards. Brissett completed 27 of 37 passes for 277 yards and a touchdown without throwing an interception.

Trey McBride was one of the biggest reasons for the offensive success.

McBride caught nine passes for 95 yards and a touchdown. His ability to consistently create production from the tight end position gives Brissett a reliable option against Seattle’s defense.

Arizona also received a touchdown from rookie running back Jeremiyah Love, while its defense and special teams created important momentum swings.

The Cardinals blocked a punt and intercepted Herbert in the fourth quarter. Those plays helped Arizona turn a competitive game into a two-score victory.

Now Arizona gets to play its home opener.

---

Home-Field Advantage Matters for Arizona

The Cardinals are returning to Glendale after winning their season opener on the road.

Their Week 2 matchup against Seattle is the team’s home opener, giving Arizona an opportunity to build momentum in front of its home crowd. The Cardinals’ official schedule confirms Seattle is the Week 2 home opponent.

The home setting becomes more important because Seattle is already dealing with a quarterback adjustment.

Lock is an experienced NFL quarterback, but this will be his first start for Seattle since 2023.

Arizona can potentially make the game uncomfortable by creating third-and-long situations and forcing Seattle to sustain long drives.

If the Cardinals avoid turnovers, they should have opportunities to stay within one score.

---

Jacoby Brissett Gives Arizona Stability

Brissett was one of the most efficient quarterbacks in Week 1.

He completed 27 of 37 passes for 277 yards and a touchdown against the Chargers without an interception. He also added 14 rushing yards.

That efficiency is important against Seattle.

The Seahawks’ defense forced three interceptions from Maye in the fourth quarter of Week 1. Arizona cannot afford to give Seattle the same opportunities.

Brissett’s ability to protect the football could be one of the most important factors in this matchup.

Arizona does not necessarily need an explosive passing game.

If Brissett consistently finds McBride and the Cardinals’ other receiving options, Arizona can keep drives alive and force Seattle’s defense to remain on the field.

That would also help Arizona’s chances of covering the spread.

---

Trey McBride vs. Seattle’s Defense

McBride is arguably the most important matchup for Arizona’s offense.

He enters Week 2 after catching nine passes for 95 yards and a touchdown against the Chargers.

Seattle’s secondary was excellent against New England, but the Cardinals present a different challenge.

McBride can operate underneath coverage, attack the middle of the field and give Brissett a high-percentage option when Seattle brings pressure.

The Seahawks’ defense cannot simply focus on the outside receivers.

That creates opportunities for Arizona to move the chains.

McBride’s performance could also determine the pace of the game. Consistent short completions would allow Arizona to maintain possession and prevent Seattle from relying heavily on its defense.

---

Marvin Harrison Jr. Has Room for Improvement

Arizona did not get a major statistical contribution from Marvin Harrison Jr. in Week 1.

Harrison caught only one pass on three targets against the Chargers.

That could change against Seattle.

The Seahawks’ defense will have to account for Harrison’s downfield ability, even if Arizona does not force the ball his way.

Simply having him on the field can create opportunities for McBride, Michael Wilson and the running game.

If Harrison produces a few explosive plays, Arizona’s offense becomes considerably harder to defend.

The Cardinals do not need him to have a huge game to cover +5.5, but a more involved Harrison would give Brissett another weapon against Seattle’s secondary.

---

Seahawks Defense vs. Cardinals Offense

This is the matchup that could determine the game.

Seattle’s defense looked excellent late against New England. The Seahawks forced three fourth-quarter interceptions and generated enough pressure to completely change the game.

Arizona, meanwhile, showed it can move the football.

The Cardinals ran 71 plays against the Chargers and produced 393 yards. Seattle ran only 48 plays against New England.

That difference in volume is significant.

Seattle’s defense may be the strongest unit on the field, but the Seahawks cannot afford to leave it on the field for long stretches.

If Arizona controls possession, the Cardinals can limit Seattle’s offensive possessions while forcing Lock to make difficult throws when he does have the football.

---

Cardinals Defense vs. Seahawks Offense

Arizona’s defense has a difficult assignment because Seattle’s offensive philosophy can change with Lock starting.

The Seahawks may lean more heavily on their running game, short passing concepts and play-action.

That approach would reduce the pressure on Lock.

Arizona’s objective should be to create obvious passing situations.

If Seattle faces third-and-long repeatedly, the Cardinals can attack Lock with pressure and force him to make decisions under stress.

Seattle’s 18.2% third-down conversion rate from Week 1 is particularly relevant.

The Seahawks cannot consistently fail to convert third downs and expect their defense to win every possession.

---

Seahawks at Cardinals Betting Prediction: Spread Analysis

The current spread is around Seattle -5.5, with Arizona listed as a 5.5-point home underdog. The total is around 41.5 points.

At first glance, the spread makes sense.

Seattle is the defending Super Bowl champion, owns an elite defense and opened the season with a win.

But the quarterback situation changes the handicap.

Darnold is out.

Lock played well in relief, but this is still a road start against a division opponent.

Meanwhile, Arizona already demonstrated that it can compete with a strong opponent. The Cardinals went into Los Angeles and won 26-14 despite entering the game as a major underdog.

The line also asks Seattle to win by at least six points.

That is a substantial margin for a team that scored only 13 points in Week 1 and now has a backup quarterback starting on the road.

For that reason, Arizona +5.5 is the preferred spread position.

---

Seahawks at Cardinals Betting Prediction: Total Analysis

The game total is currently around 41.5 points, making this one of the lower projected-scoring games on the Week 2 schedule.

There are several reasons to consider the Under.

Seattle scored only 13 points in Week 1.

Arizona scored 26, but the Cardinals benefited from several critical Chargers mistakes.

Seattle’s defense should present a more difficult challenge for Brissett than the Chargers did.

At the same time, Lock’s presence could reduce Seattle’s offensive ceiling.

The Under also benefits if Arizona plays conservatively with a lead.

A game featuring two strong defensive units and a backup quarterback can become increasingly valuable for the Under as the game progresses.

The biggest threat to this pick is an early defensive or special-teams touchdown.

Seattle and Arizona both showed the ability to generate turnovers and create field-position swings in Week 1.

Still, the matchup profiles as a relatively low-scoring divisional contest.

Secondary Bet: Under 41.5

---

Why Arizona Can Cover the Spread

There are four primary reasons to consider the Cardinals.

1. Seattle is without Sam Darnold

Darnold is officially out, and Lock will start.

Lock’s Week 1 performance was encouraging, but there is still uncertainty about how Seattle’s offense will perform with him starting from the opening snap.

2. Arizona’s offense was productive

The Cardinals generated 393 yards in Week 1 and converted 42.9% of their third downs.

3. The Cardinals are at home

This is Arizona’s home opener, while Seattle is playing its first road game of the season.

4. The spread is substantial

Arizona does not necessarily need to win.

The Cardinals only need to stay within five points to cash the +5.5 side.

A 23-20 Seattle victory, for example, would still result in an Arizona cover.

---

Why Seattle Could Still Win

Backing Arizona does not mean ignoring Seattle’s strengths.

The Seahawks remain a legitimate threat because of their defense.

Seattle forced three interceptions in the fourth quarter against New England and allowed only 10 points.

Lock also showed that he can step into the offense and make enough plays to win.

Smith-Njigba gives him an elite receiving option after catching eight passes for 122 yards and a touchdown in Week 1.

Seattle’s defense could also create short fields.

If the Seahawks win the turnover battle again, the Cardinals could struggle to maintain their offensive rhythm.

That is the primary reason Arizona +5.5 is preferable to simply taking the Cardinals moneyline.

---

The Turnover Battle Could Decide the Game

Turnovers were central to both teams’ Week 1 victories.

Seattle’s defense produced three fourth-quarter interceptions against New England. Arizona intercepted Herbert and also benefited from a blocked punt against the Chargers.

Both teams finished Week 1 without an offensive turnover according to the available statistical comparison.

That makes turnover variance important.

If Seattle forces two or three turnovers again, the Seahawks could win comfortably.

If both teams protect the football, the matchup becomes more dependent on sustained drives, field position and quarterback efficiency.

That scenario favors the underdog because Arizona has already shown it can generate enough offense to stay competitive.

---

Seahawks at Cardinals Betting Prediction: Best Bet

The best bet is Arizona Cardinals +5.5.

The number gives Arizona enough room to absorb a close loss.

Seattle’s defense makes the Seahawks dangerous, but the offensive situation is different with Lock starting from the opening snap.

Arizona’s offense also enters the game with strong momentum after producing 26 points and 393 yards against the Chargers.

The Cardinals have a legitimate path to covering even if Seattle’s defense controls portions of the game.

A close, low-scoring divisional matchup is the preferred script.

Best Bet: Cardinals +5.5

Secondary Bet: Under 41.5

Projected Score: Cardinals 23, Seahawks 20

---

Seahawks at Cardinals Betting Prediction: Projected Game Script

The first half could be relatively conservative.

Seattle should try to establish its running game and protect Lock from obvious passing situations. Arizona should attempt to use Brissett’s accuracy and McBride’s ability to move the chains.

A halftime score around 10-10 would fit the matchup.

The second half should open up slightly.

Seattle has the defensive advantage, but Arizona’s offense should be able to generate enough sustained drives to avoid falling behind by multiple scores.

A late Seattle push is possible, particularly if the Seahawks’ defense creates a turnover.

However, Arizona’s home-field advantage and offensive efficiency should keep the Cardinals within the number.

The projected final score is:

Arizona Cardinals 23, Seattle Seahawks 20

That score produces 43 total points, slightly above the current 41.5 total. Because of that, the total recommendation should be treated as the more conservative position only if the number remains around 41.5; a significant move upward would reduce the value of the Under.

Key Players to Watch

Drew Lock — Seahawks QB

Lock completed 16 of 22 passes for 187 yards and a touchdown after replacing Darnold in Week 1.

His ability to avoid turnovers is crucial.

Jaxon Smith-Njigba — Seahawks WR

Smith-Njigba caught eight passes for 122 yards and a touchdown in Week 1.

He is the obvious focal point of Seattle’s passing game.

Jacoby Brissett — Cardinals QB

Brissett completed 27 of 37 passes for 277 yards and a touchdown against Los Angeles.

His ball security will be critical against Seattle.

Trey McBride — Cardinals TE

McBride caught nine passes for 95 yards and a touchdown in Week 1.

He could be Arizona’s most important matchup weapon.

Marvin Harrison Jr. — Cardinals WR

Harrison had only one catch in Week 1, leaving plenty of room for a larger role against Seattle.

Final Seahawks at Cardinals Betting Prediction

The Seahawks at Cardinals Betting Prediction comes down to the difference between Seattle’s defense and Arizona’s offensive situation.

Seattle has the stronger defensive profile after forcing three interceptions in the fourth quarter against New England. The Seahawks also have one of the league’s most talented receiving options in Smith-Njigba, who produced 122 yards and a touchdown in Week 1.

However, Darnold’s absence changes the equation.

Lock is capable of running the offense, and his Week 1 performance was encouraging. But Seattle is now being asked to win on the road by more than a field goal with a quarterback who did not enter the season as the starter.

Arizona showed considerable offensive efficiency in Week 1. Brissett completed 27 of 37 passes for 277 yards without an interception, while McBride produced nine receptions for 95 yards and a touchdown.

The Cardinals also get their home opener after winning on the road.

That combination makes Arizona +5.5 the preferred betting pick.

The projected result is a competitive NFC West matchup with Arizona staying within the number.

Best Bet: Arizona Cardinals +5.5

Secondary Bet: Under 41.5

Projected Score: Arizona Cardinals 23, Seattle Seahawks 20
