The Cardinals' defensive players take great pride in stopping running backs, as we saw late last season in the "Skittles" game in Seattle.

After limiting Marshawn Lynch to 71 yards on 18 carries, a few of the Cardinals defenders ate Skittles on the sideline to mock Lynch, who enjoys the candy, and Seahawks fans, who enjoy tossing the candy on the field in celebration.

The Cardinals (6-1) will be just as happy Sunday if they can limit the damage done by Cowboys running back DeMarco Murray.

He's rushed for more than 100 yards in each of the Cowboys' eight games. No other running back in NFL history opened a season with more than six 100-yard games.

"No one has done what he's done," Cardinals coach Bruce Arians said, "so you have to take your hat off to him and say, 'Great job.'"

The Cardinals have made stopping the run a priority since Arians and defensive coordinator Todd Bowles arrived in 2013. The Cardinals were the top-ranked defense against the run last year, and they rank third this season, yielding an average of 77.9 yards a game.

The Cardinals haven't allowed an opposing runner to gain 100 yards since the 49ers' Frank Gore had 101 in the sixth game last year. That's a 17-game streak. Only the Ravens have a longer one, 18.
