The market spread of -7.5 for the 49ers is dramatically softer than the model’s projected -30.5, delivering an edge of -23.0 in favor of the home side. Both the market and the model agree the pick side is home, and the strength is listed as play, setting the stage for a decisive betting opportunity at Levi’s Stadium, where the 49ers sit 2-0 (1-0) and the Cardinals sit 1-1 (0-1).
