Cardinals vs 49ers Prediction
The Cardinals won both meetings against the 49ers last season. At home by 47-24 and on the road by 24-23, covering the spread in both. The 49ers have won the four meetings before that, but the Cardinals are 3-2 in their last 5 trips to San Fran. Over is 6-1 in their last 7 meetings.
In this Cardinals vs 49ers Prediction, the 49ers are coming as -2.5-point home favorites, with the total set at 45 points. Both teams are undefeated in this young season, with the 49ers having covered the spread in both, and are playing their first game in front of their home crowd. Arizona’s only home win this season was against a weak New Orleans squad, and while both teams have similar offensive and defensive numbers, the 49ers are far better in yards for and against. The value lies with the home team in this matchup, so take the San Francisco 49ers and lay the -2.5 points at home.
