ANALYSIS: The weekend’s second-highest total belongs in the 40s. The Cardinals’ RB room has been thinned out, leaving little former seventh-round draft pick Eric Benjamin as the main man. Even with a full cast at the position, Arizona has started slowly on offense, having failed to score in the first quarter all season. The 10-1 against-the-spread road streak can be traced to defense. Last week, the Cardinals held the Eagles to their lowest yardage and point totals of the year. And their past three games have not topped 42. Seattle has flexed offensive muscle, but can recycled QB Geno Smith continue his hot stretch?
