DeMarco Murray lacks a good answer for the Dallas Cowboys’ lack of a running game. Maybe the St. Louis Rams provide one.

Murray received his first extended playing time against the Rams two years ago and he announced his presence by passing Tony Dorsett Emmitt Smith and Jim Brown in the record books. Adrian Peterson was the only running back Murray failed to pass that day.

With Felix Jones nursing a sprained ankle that day and Tashard Choice not providing the needed spark Murray gained 253 yards including a 91-yard touchdown run. He set the team rookie rushing record formerly held by Dorsett the team single-game rushing record formerly held by Smith and he gained the most rushing yards ever against the Rams topping Brown.

“It was a good game” Murray said Friday. “I just remember offensively we were clicking that day and offensively we had a great day that day.”

The Cowboys would love to relive the past.

Since then Murray has only three 100-yard games. He is averaging 70.8 yards per game and 4.4 yards per rush — lower than his career average of 4.8 — in the 19 games he has played since.

Murray hasn’t had a 100-yard game since he opened the 2012 season with 131 yards on 20 carries against the Giants.

“I don’t know what the stats are. I never look at stats” said Murray who has missed nine games with injuries in his three seasons. “Am I getting touchdowns? Am I getting yards? I’m just looking at the only stat that really matters and that is wins and losses.”

The Cowboys vowed to run it more and run it better than they did last season when they set the team record for fewest rushing yards in a 16-game season. But they are running nowhere fast.

The Cowboys are tied for 26th in rushing with 124 yards in two games and they are averaging only 3.2 yards per rush. It begs the question: Does success in the running game come first or is it a commitment to run?

“You have to be committed to doing it but you also have to have some success doing it” Cowboys coach Jason Garrett said. “It’s our job as coaches to find things that are good. It’s our players’ job to execute those things. And you just have to be persistent throughout the game.”

The Cowboys ended last week’s 17-16 loss to the Chiefs with 12 consecutive passes. With Dez Bryant Miles Austin and Jason Witten as receiving threats it is tempting to get into a pass-first mentality.
