Despite being 6-7, the Rams are a four-point betting favorite over the visiting Arizona Cardinals, who lead the NFC West with an impressive 10-3 record.

Other than the obvious thing — the betting line is directly related to wagering trends — why are the Rams favored?

Let's take a look:

• The Cardinals are unbeaten at home but only 3-3 on the road. The Cardinals rank 24th in the NFL with a road-scoring average of 19.7 points per game, and they are 26th with only 11 touchdowns from scrimmage in road games. They rank 29th with an average of 3.3 yards per carry in road games, 25th in net passing yards per road game, and are 31st in average yards from scrimmage (299.3) when away from home.

• Home or away the AZ offense has slowed, scoring only two touchdowns in the last 15 quarters of play.

• Arizona QB Drew Stanton is 1-3 on the road with a 63.5 passer rating. That 63.5 road passer rating is the worst among NFL quarterbacks. At least until now, Stanton has been a different quarterback on the road. He's been very good at home, having gone 4-0 as a starter with a 97.7 passer rating.
