Cardinals vs 49ers Prediction

In this Cardinals vs 49ers Prediction, the 49ers are coming as -8.5 home favorites. The 49ers have been undefeated this season, having covered the spread in both games and have the 4th-best offense in the NFL and a +21 point differential. The Cardinals just lost by 24 points at home by the Seahawks and now have to travel to San Francisco, where they have won only once in their last four visits. Their offensive line has been shaky at best and I don’t trust them to keep this close. Take the 49ers and lay the -8.5 points at home.
