**The Rams lost, 23-13, in San Francisco last Sunday, snapping their two-game win streak in the process. St. Louis is now 0-7 in 2013 when failing to score more than 24 points (5-0 when scoring 25 or more points).
**Arizona dropped a 24-21 decision in Philadelphia last Sunday, ending its season-high win streak at four straight games. The Cardinals are also 5-0 when putting at least 25 points on the scoreboard this season (2-5 when scoring 24 or fewer points).
**St. Louis outscored Arizona, 14-0, in the fourth quarter of these clubs’ first meeting of the season, on the way to a 27-24 victory at Edward Jones Dome in Week 1. The Rams have won three straight and four of the last six games versus the Cardinals overall.
**Zac Stacy ran the ball 19 times for 72 yards last Sunday versus the 49ers, but was kept out of the end zone for the first time in his last four games. Stacy has 696 yards on the ground overall this season — second among all NFL rookies (Eddie Lacy — 822).
**With 302 yards through the air in Week 13 against the Eagles, Carson Palmer has now thrown for at least 300 yards in three straight games, tying his personal best. Palmer also had three scoring tosses last Sunday, giving him five straight games with multiple touchdown passes — the first Cardinals’ QB to accomplish that feat since Kurt Warner did so from November 1-December 6, 2009.
**Dating to Week 2 last season, Arizona is 0-8 versus its divisional opponents and 11-8 against all others. The last time the Cardinals defeated an NFC West team, was Week 1 in 2012 (beat Seattle 20-16).
