The improving Rams defense against the run is currently ranked 13th in the 32 team National Football League. But the Rams defenders will get quite a test this coming Sunday in Buffalo. The Bills have a running back tandem to contend with. C.J. Spiller averages 6.6 yards per carry and has gained 907 yards on the season. The Bills other running back is Fred Jackson who has gained 423 yards in 2012, good for a 4.0 average per rush. So how do the Rams combat the Buffalo running attack?
