The Cardinals are only 2-4, but their two wins have been big ones.
Specifically, they've been the two biggest upsets in the NFL this season: When the Cardinals beat the Rams on Sunday, they were 12.5-point underdogs. That was the biggest upset of the year, surpassing the Cardinals' Week 1 win over the Chargers, when they were 9.5-point underdogs.
There have only been seven games this season when the point spread was more than nine points. Those two games that the Cardinals won as underdogs, and five other games in which the underdogs lost by a combined 72 points.
Both of the Cardinals' wins this season have been at SoFi Stadium in Los Angeles, where they have two wins, the Rams have one and the Chargers have none. Don't bet against the Cardinals, at least not in Los Angeles.
