Seattle Begins Its Title Defense With a Win

The Seahawks entered 2026 carrying enormous expectations after winning Super Bowl LX, and their first regular-season game showed that defending a championship is rarely easy.

Seattle opened the season against the New England Patriots at Lumen Field and came away with a tense 13–10 victory.

It wasn’t necessarily the explosive performance Seahawks fans might have expected, but championship teams often have to win games in different ways.

Seattle found a way.

Now the challenge changes dramatically.

Instead of playing at home, the Seahawks must travel to Arizona for their first divisional game of the season.

The atmosphere will be different, the opponent will be confident, and the stakes will feel significantly higher.

Seattle knows that starting 2–0 would be valuable.

Starting 1–0 in the NFC West would be even better.

Arizona Has Momentum of Its Own

The Cardinals will not be intimidated by Seattle’s championship credentials.

Arizona opened its season on the road against the Los Angeles Chargers and delivered an impressive 26–14 victory.

Now the Cardinals return to State Farm Stadium for their home opener with an opportunity to make an even louder statement.

Beat Seattle, and Arizona moves to 2–0.

More importantly, the Cardinals would earn an early divisional victory against the defending Super Bowl champions.

That would immediately create attention around Arizona.

The Cardinals will want to establish energy from the opening drive, using the home crowd to put pressure on Seattle and prevent the Seahawks from settling comfortably into the afternoon.

An early Arizona touchdown could transform the atmosphere inside State Farm Stadium.

Seattle’s job will be to prevent that from happening.

A Familiar NFC West Rivalry

There is no mystery between these franchises.

Seattle and Arizona meet twice every regular season, and their games frequently become unpredictable regardless of records.

The Seahawks have enjoyed considerable recent success in the series.

Seattle has won eight consecutive games against Arizona, including both meetings during the 2025 regular season.

The Seahawks won 23–20 in Arizona before later producing a dominant 44–22 victory at Lumen Field.

Arizona therefore enters Sunday’s game with more than an undefeated record at stake.

The Cardinals have an opportunity to finally end Seattle’s lengthy winning streak in the rivalry.

That should add another layer of intensity.

What Could Decide the Game?

Turnovers could be the biggest factor.

Divisional games are often decided by a handful of plays, and giving an opponent a short field can completely change the momentum.

Seattle cannot afford careless mistakes on the road.

Arizona cannot afford to hand extra possessions to the defending champions.

Third-down efficiency will also be crucial.

The Seahawks will want to sustain drives, control possession and keep Arizona’s offense on the sideline. The Cardinals, meanwhile, need to force Seattle into uncomfortable situations and allow the home crowd to become a factor.

Red-zone execution could also separate these teams.

When opportunities appear inside the opponent’s 20-yard line, touchdowns instead of field goals may become essential.

In a rivalry game, leaving points on the field can be costly.

Seattle Faces Its First Road Test

Sunday begins an important stretch for the Seahawks.

After opening the season at home, Seattle now starts back-to-back road games, first visiting Arizona before traveling across the country to face the Washington Commanders in Week 3.

That makes this trip particularly important.

A victory would give Seattle a 2–0 start and valuable momentum before another road challenge.

Arizona has a different opportunity.

The Cardinals can defend their home field, remain undefeated and announce themselves as a serious early contender in the NFC West.

Something has to give.

Two 1–0 teams.

Two NFC West rivals.

One defending Super Bowl champion.

And one Arizona team determined to end a long losing streak against Seattle.
