Arizona at St. Louis

A pair of strong defensive teams clash in the NFC West -- and one weak offense. Arizona has a terrific defense, #5 in the NFL in yards allowed and #10 in points. Arizona is 5-2 UNDER the total on field turf. This is a tough situational spot for the Cardinals, their second straght divisional road game and their fourth road game in five weeks. They are on a 2-4 spread run and run into a hard-hitting St. Louis defense. The Rams are #11 in the NFL in points allowed, #13 in yards, with a strong pass rush that can get after the QB. That will be a plus here as Arizona just lost RB Chris Johnson, a huge part of their improved offense. The Rams get up for these divisional games, already winning at Arizona as a big dog, and are 7-1-1 ATS at home against a team with a winning road record. St. Louis has a conservative, ball control offense on a 6-1 run UNDER the total, plus 34-16 UNDER in December. And when these rivals meet the dog is 6-2 ATS and the UNDER is 5-2 on this field. Back St. Louis and the UNDER.
