Arizona didn't win because Mike McDaniel's offense is broken. The Cardinals won because Jacoby Brissett played a cleaner game than the franchise quarterback on the other sideline, and because a defense nobody argued about in August took the ball away.
The scoreboard says 26-14, the biggest upset of NFL Week 1. The market says the Chargers were 9.5-point favorites. Both are true. Both are now being read as proof that the McDaniel experiment in Los Angeles is already a problem. That read is too fast.
Brissett went 27-of-37 for 277 yards, one touchdown and zero interceptions, a 103.1 passer rating. Trey McBride caught 9 of 13 targets for 95 yards and a score, functioning as the entire passing game. Tyler Allgeier carried 17 times for 61 yards and Jeremiyah Love added 11 for 41 and a touchdown. That is the blueprint for a heavy underdog: no turnovers, a tight end who never leaves the field, and enough run game to keep the clock and the opposing offense on the sideline.
Then there is Andrew Wingard's interception. Brissett threw none, so that ball came off Justin Herbert. Jordan Burch recorded a sack, and Jack Gibbens and Budda Baker split another. Two sacks and a takeaway from a group that was an afterthought in the Week 1 preview.
None of this absolves Herbert. He struggled to find rhythm in a new system, and that is the story everyone will chase this week. It just isn't the whole story. Week 1 under a first-year coordinator is the least predictive sample the NFL offers, and the Chargers lost to a team that executed better in the margins, not to a scheme that cannot work.
My call: the overreaction to McDaniel will be louder than the evidence supports, and Arizona's defense will be taken more seriously by Week 4 than it was by the betting market in Week 1. The Chargers are fine. The Cardinals are better than 9.5 points, and that is the takeaway nobody wants to write.
