The Cardinals offense has been hitting on all cylinders lately, and on paper at least, Arizona is capable of approaching 40 points vs. a bad Rams defense in a dome. Go Over in St. Louis.
The Arizona Cardinals have been on fire offensively, and playing inside a dome vs. a terrible St. Louis Rams defense, the Cardinals are capable of scoring close to 40 points in this game themselves, making the Over worth a long look here.

The Over is now an incredible 40-18 in the last 58 Arizona road games, and quarterback Kurt Warner and receivers Larry Fitzgerald and Anquan Boldin have been with the club for much of that stretch, making the trend relevant.
The Cardinals are averaging 25.4 points per game overall this year, but remember that they were held below 20 points in two of their first three games. In their six games since a 31-10 loss to the Indianapolis Colts in a Sunday night game, Arizona has averaged 28.7 points and a whopping 378.0 yards per game, and their running game has improved in recent weeks as Beanie Wells has become more involved in the offense, making their lethal passing game even more dangerous.
This makes for a nightmarish matchup for a St. Louis defense that is ranked 28 in the NFL in total defense, allowing 378.6 yards and 27.7 points per game. Yes, the Rams stood up surprisingly well to Drew Brees and the New Orleans Saints last week, but the end results was a disheartening loss, and we simply do not see the St. Louis defense matching that intensity here.
The biggest threat to this Over is the Rams offense, but they did put up 23 on the Saints and they are capable of scoring some late garbage points here should Arizona open up a big lead.
Besides, the Rams may not need to score much for this game to go Over if the Cardinals have as much success offensively as we expect.
Free Pick: Cardinals, Rams Over 46½ (-110)
