Arizona Cardinals vs Los Angeles Chargers Picks, Prediction, Odds, and Line Movement for Sunday September 13 2026

Sunday's Arizona Cardinals vs Los Angeles Chargers picks revolve around whether Los Angeles deserves to lay nearly double digits in its first game under new offensive coordinator Mike McDaniel. The Chargers are favored by 9.5 at SoFi Stadium, while the total is 47.5. Los Angeles was available at -10.5 earlier, so the market has already moved a full point toward Arizona.

Justin Herbert gives the Chargers a major quarterback advantage over Jacoby Brissett, but a 9.5-point spread asks Los Angeles to win comfortably rather than simply control the game. Arizona is beginning the Mike LaFleur era with low expectations after a 3-14 season, yet the Cardinals can still be competitive if they protect Brissett, shorten the game and prevent Herbert from generating easy explosives.

Arizona Cardinals vs Los Angeles Chargers Preview

The Chargers' most important change is the arrival of McDaniel to coordinate Herbert's offense. Herbert already has the arm talent to attack any area of the field, and McDaniel's motion-heavy structure should create easier leverage throws and force Arizona to communicate before the snap. The early-season question is not whether the concepts fit. It is how quickly the offense can execute them at full speed.

Los Angeles also expects to have Joe Alt and Rashawn Slater back on the offensive line. Their presence matters because Herbert becomes far more difficult to defend when the Chargers can protect with five and release the full route combination. Arizona cannot count on pressure arriving quickly enough to save coverage mistakes.

Brissett is expected to start for a Cardinals team beginning a reset under LaFleur. His job is straightforward: avoid turnovers, get the offense into the correct protection and make Los Angeles defend long possessions. Brissett is not likely to win a pure shootout with Herbert, but he has enough experience to keep Arizona functional if the offensive line gives him time.

Arizona also drafted running back Jeremiyah Love third overall, but his high-ankle sprain remains one of the important personnel situations to monitor before Sunday. The Cardinals do not need to assume a full workload from him to establish the run. They need enough rushing efficiency from the available backfield to keep the Chargers from attacking Brissett on every obvious passing down.

The move from Los Angeles -10.5 to -9.5 is meaningful because double-digit NFL spreads create a very different burden for the favorite. At +9.5, Arizona can lose by a touchdown plus a field goal attempt that misses or by any one-score margin and still cover. The Chargers may be clearly superior and still fail to create the separation required by the market.

Matchup Breakdown

Arizona's biggest defensive problem is containing Herbert without committing too many bodies to the pass rush. McDaniel can punish aggressive fronts with screens, motion and quick throws, especially if the Chargers' tackles are healthy. The Cardinals need to rally to the ball and force Los Angeles to finish drives rather than allowing five-yard completions to become 25-yard gains.

The Cardinals' offensive approach should be the opposite of aggressive. Brissett needs to take the underneath throws, use play action and keep the clock moving. Arizona's defense has a better chance of staying competitive if Herbert has fewer possessions. A three-and-out followed by a quick Chargers touchdown is the game script that can destroy the underdog early.

Los Angeles does not need to chase points once it gets ahead. Jim Harbaugh has consistently preferred physical football when his team controls the game, and McDaniel's system can still create efficient rushing opportunities. If the Chargers lead by seven to 10 points in the second half, they can reduce risk and make Arizona drive the length of the field. That helps the underdog spread and the Under at the same time.

The total has moved upward from around 46.5 to 47.5 even as the spread has moved toward Arizona. That combination suggests the market expects the Cardinals to contribute more than a minimal offensive output. The Under becomes more attractive at the higher total because the Cardinals' best path is still slow and possession-oriented rather than explosive.

Arizona also has a coaching incentive to keep the opener manageable. LaFleur is not likely to expose Brissett to unnecessary deep-dropback risk simply to chase style points. If the Cardinals remain within two scores, there is no reason to abandon the run or hurry-up offense. That can drain valuable minutes even when Los Angeles is controlling field position.

The Chargers also have to manage expectations attached to McDaniel's debut. Motion and spacing can create cleaner reads, but a new system still requires communication along the offensive line and precise timing between Herbert and his receivers. A couple of early procedural mistakes or stalled red-zone possessions can be enough to keep a large underdog alive. Arizona's margin for error is smaller, yet that is exactly why taking more than a touchdown is preferable to trying to predict an outright upset.

Game Thesis: Herbert should lead the Chargers to the win, but Los Angeles does not need to win by double digits to validate its matchup advantage. Arizona can keep the game inside the number by protecting Brissett, shortening possession count and forcing the Chargers to finish drives in the red zone rather than allowing repeated explosives.

Cardinals vs Chargers Best Bet - Spread: Arizona +9.5 (-105)

Arizona +9.5 is the preferred bet because the current spread has dropped from double digits while still giving the Cardinals substantial cushion. Los Angeles can control the game and win by seven without threatening the wager. That is valuable in Week 1, when offensive timing under a new coordinator may not be fully polished from the opening drive.

The risk is obvious. If Arizona cannot protect Brissett and the Chargers create short fields, the matchup can become one-sided quickly. Love's availability also affects Arizona's ability to sustain the run game. The wager is strongest at +9 or better and becomes less appealing if the market drops through +8.5.

Cardinals vs Chargers Total Pick: Under 47.5 (-118)

The Under matches the way Arizona should approach the game. The Cardinals can keep the score manageable by extending possessions and refusing to turn the opener into a track meet. Los Angeles has the offensive ceiling to score in the high 20s, but Arizona does not need to reach the mid-20s for the game to stay below 47.5.

Prediction: Los Angeles Chargers 27, Arizona Cardinals 20
