Useful takeaways from this story.

Arizona’s defense limited the Chargers to 14 points and forced three sacks and two takeaways, but coach Mike LaFleur says there’s “a lot to clean up.”

Offense was efficient: Jacoby Brissett threw for 277 yards and a touchdown, and rookie RB Jeremiyah Love contributed 41 rushing yards and a touchdown despite limited practice.

LaFleur became the first non-interim Cardinals coach to win his debut since 1973, but he warned against overreacting to one game.

# Game snapshot Chargers. Entering the game as 9.5-point underdogs after a 3-win 2025 season, the Cardinals surprised by containing Justin Herbert and the Chargers' offense to 268 yards and 14 points.

# Defense held, coach still sees work Head coach Mike LaFleur praised the defense's effort and credited defensive coordinator Nick Rallis for a strong game plan. LaFleur said, "I thought as the game went on they just got better and better," and called the performance "clean on their end." He also added there is still work to do: "But overall, very pleased with them but again a lot to clean up."

# Who stood out on defense

  • Walter Nolen III drew attention for his disruptive play even while seeing double and triple teams. LaFleur said, "He was disruptive. I thought he played hard and that's what's great about him."
  • Dante Stills' fourth-down play and a sack marked a key momentum swing. Stills noted the personal significance: "It definitely felt good because I haven't had a sack in a whole year."
  • Safety Andrew Wingard forced a fumble on running back Omarion Hampton and later intercepted Herbert on a deep shot with under 10 minutes remaining. That interception helped seal the win.

Wingard pushed back on external criticism of the defense in a postgame comment: "Everyone has been trashing this defense, trashing coach Rallis… I'm just happy for all these guys."

# Offense: efficient and complementary The offense moved the ball efficiently behind veteran QB Jacoby Brissett and rookie running back Jeremiyah Love. Brissett, making his first season-opening start, completed passes for 277 yards with a touchdown, was not intercepted and was sacked once. LaFleur said, "I thought Jacoby was solid. I thought for the most part the ball got where it was supposed to."

Rookie third-overall pick Jeremiyah Love made an immediate impact despite limited practice because of an ankle sprain. He rushed 11 times for 41 yards and a touchdown and caught two passes. Starter Tyler Allgeier led the ground game with 61 yards on 17 carries.

LaFleur highlighted a play before halftime where Brissett threw the ball away under pressure and noted the quarterback's high standard: Brissett was "mad at himself for not getting rid of it sooner," which LaFleur described as "just a veteran being a veteran."

# Coach's perspective and context

The win marks LaFleur's debut victory as a non-interim Cardinals head coach — the first since 1973 — but he warned the team and fans against reading too much into a single game. He repeatedly noted there is more to clean up on both sides of the ball.
