Arizona Cardinals vs Los Angeles Chargers Prediction, Odds & Best Bet - September 13, 2026

Featured pick: Arizona Cardinals moneyline +420 at FanDuel. The case begins with price rather than a claim that Arizona is the better team. A +420 moneyline requires the Cardinals to win more than 19.2% of the time to clear the listed break-even point. The supplied projection puts Arizona at 19.7%, leaving a 0.5% edge and 0.026 expected value per unit.

That advantage is narrow, and the Low confidence designation matters. Los Angeles is priced at -500, while the available spreads make the Chargers favorites by 8.5, 9, 9.5, or 10 points depending on the book. Arizona is therefore being asked to overturn a substantial market expectation, not merely remain competitive or cover a spread.

The appeal of Arizona +420 is that the payout compensates for a low projected win rate. Both teams enter at 0-0, with Gardner Minshew II listed at quarterback for Arizona and DJ Uiagalelei for Los Angeles. With no completed 2026 game reflected in either record, quarterback execution and the final availability reports take on particular importance. The selection clears the stated threshold, but only by half a percentage point; it should be treated as a measured underdog play, never a lock.

Arizona's route to an outright win starts with Gardner Minshew II managing enough productive possessions to prevent Los Angeles from controlling the game as a heavy favorite. The Cardinals cannot rely on the cushion supplied by Arizona +8.5, +9, +9.5, or +10 because the featured moneyline requires them to finish ahead. Sustaining drives, protecting the football, and converting scoring opportunities are consequently more important than keeping the final margin respectable.

Arizona's availability list creates concerns on both offense and defense. Guard Isaiah Adams is Questionable, so his final status has direct relevance to protection around Minshew. Running back Jeremiyah Love is Questionable with a sprain, which could affect how Arizona distributes touches and structures its offensive possessions. No assumptions should be made before the inactives are confirmed, but losing either player would reduce the margin for error attached to Cardinals +420.

The defensive front is already dealing with definite absences: defensive tackles Kaleb Proctor and Zachary Carter are on Injured Reserve. Their absence is a concrete concern against a Los Angeles offense quarterbacked by Uiagalelei, particularly if the Chargers can remain balanced and avoid obvious passing situations. Cornerback Garrett Williams is also Questionable. Arizona needs enough resistance at each level to create punts, sacks, takeaways, or failed fourth-down possessions; long Chargers scoring drives would make the upset considerably harder.

Los Angeles is the clear market favorite. The Chargers are -500 on the moneyline, and every supplied spread makes them at least an 8.5-point favorite. That pricing says the market expects DJ Uiagalelei and the home team to win comfortably more often than not at SoFi Stadium. It also explains why the Arizona projection can support +420 while still recognizing that a Chargers victory is the single most likely result.

The Chargers have their own availability questions. Linebacker Tuli Tuipulotu, cornerback Deane Leonard, and safety RJ Mickens are all Questionable. If any are inactive, Los Angeles could have less defensive flexibility against Minshew and the Arizona offense. Wide receiver Brenen Thompson and running back Keaton Mitchell are also Questionable, creating potential uncertainty around Uiagalelei's available skill-position group.

Los Angeles does not need to cover -8.5, -9, -9.5, or -10 to defeat the featured selection; any Chargers win beats Arizona +420. That distinction is the primary danger for underdog bettors. Even if Arizona plays a competitive game, Los Angeles can validate its moneyline favorite status through one decisive fourth-quarter drive or one defensive stop. The Chargers' task is simpler: avoid giving Arizona short fields, make Minshew sustain full-field possessions, and exploit an Arizona interior defense missing Proctor and Carter.

The decisive matchup is Arizona's offense under Gardner Minshew II against the Los Angeles defense, with availability potentially determining how viable the upset becomes. Arizona must score enough to win outright, and that becomes more difficult if Isaiah Adams cannot play or if Jeremiyah Love's sprain keeps him inactive. Minshew would then have less support around him in a matchup where failed drives carry a high cost.

On the other side, the statuses of Tuli Tuipulotu, Deane Leonard, and RJ Mickens could influence how much pressure and coverage resistance Los Angeles can present. If all three are available, the Chargers may be better positioned to force Arizona into long-yardage situations and limit explosive scoring possessions. If one or more are inactive, the Cardinals could have a more realistic opportunity to keep Minshew comfortable and extend drives.

Uiagalelei's matchup with Arizona's depleted defensive-tackle group is equally important. Proctor and Carter are on Injured Reserve, while Garrett Williams remains Questionable at cornerback. Arizona +420 needs the Cardinals defense to prevent Los Angeles from turning that personnel uncertainty into steady scoring drives. If Uiagalelei operates without disruption and the Chargers repeatedly finish possessions with points, Arizona's modest projected chance will shrink quickly.

The game total sits at 47 or 47.5. Those numbers do not provide a direct reason to bet the moneyline, but they frame the scoring environment available in the market. Arizona's cleanest upset path is not tied to a declared over or under; it is tied to winning key possessions, keeping the quarterback matchup competitive, and preventing the favorite from separating on the scoreboard.

Kingpin's 19.7% projection for Arizona is only slightly higher than the 19.2% break-even probability at +420. The difference is 0.5%, with expected value listed at 0.026 per unit. That is enough to support the exact selection, but it is not a broad rejection of the Chargers' favorite status.

The wider market strongly prefers Los Angeles. The Chargers are -500, and their spread ranges from -8.5 at -110 to -10 at -110. Los Angeles -9.5 is available at +100, while Arizona prices include +9.5 at -105 and the other listed spread options at -110. These numbers show a meaningful distinction between backing Arizona to cover and backing Arizona to win. The +420 pick accepts the more difficult condition in exchange for the larger return.

Price discipline is crucial because the projected margin is so thin. At the quoted +420, the comparison is 19.7% versus 19.2%. A materially shorter Arizona price would raise the required break-even probability and could remove the entire 0.5% advantage. The pick is therefore Arizona Cardinals +420, not an endorsement of Arizona at any available number.

• A materially worse Arizona Cardinals moneyline than +420 would change the probability comparison. With only a 0.5% projected edge, a shorter price could eliminate the reason to play the Cardinals.
• A change from Gardner Minshew II as Arizona's listed quarterback or from DJ Uiagalelei as Los Angeles' listed quarterback would require the matchup to be reassessed before backing Arizona +420.
• Isaiah Adams and Jeremiyah Love both being inactive would create additional concern for Minshew's protection and Arizona's offensive options, weakening the Cardinals' upset route.
• Garrett Williams being inactive while Tuli Tuipulotu, Deane Leonard, RJ Mickens, Brenen Thompson, and Keaton Mitchell are all available would tilt the availability picture toward Los Angeles and make Arizona +420 less attractive.
• Any late information materially changing the expected roles of Minshew or Uiagalelei would matter more than a minor spread difference because the featured selection requires an outright Arizona victory.

Official inactives close to kickoff should be treated as a final checkpoint. The current selection remains Arizona Cardinals +420, but its narrow edge leaves little room for an adverse price or personnel change.
