Before he had taken a snap of significance, DeMarco Murray was the Cowboys' golden boy in waiting. They talked glowingly about their third-round pick in camp, mentioning how special he could be. Now that Murray has broken the club's rushing record with a 253-yard performance against the Rams, there has been a more measured tone when team officials speak of the rookie. Not that they are not happy — far from it. Murray was showing exactly the kind of burst they thought he had when they first saw him running the Cowboys' plays. But they also know that Murray, who had a long history of injuries in college, has a way to go before he proves himself to be an every-down back. The Cowboys still want Felix Jones, when he returns from a high ankle sprain, to take a big chunk of the rushing game, and Phillip Tanner still factors in, too. Murray has great upside, but the team is trying its best not to get ahead of itself with the rookie at this point.
