Murray runs roughshod over Rams again as Cowboys roll to easy win DeMarco Murray found the perfect antidote for his recent malaise: the St. Louis Rams. Murray rushed for 175 yards and a touchdown two years after torching St. Louis with a franchise record as a rookie, and Tony Romo threw for three scores in a 31-7 victory Sunday. Murray's first 100-yard game in more than a year started with a 14-yard run on Dallas" first offensive play, and he had plenty of open space on a 36-yarder to start Dallas" second drive to a 10-lead late in the first quarter. Sam Bradford, Murray's old college teammate at Oklahoma, didn't have nearly as much room to operate. The Cowboys (2-1) sacked him four times in the first half and had six in total after St. Louis (1-2) hadn't allowed a sack in four games dating to last season. It was the longest streak for the Rams since John Hadl was under centre for a division champion in 1973. Bradford still went 29 for 48 and was not intercepted. DeMarcus Ware had two sacks and broke Harvey Martin's 30-year-old franchise record of 114. The Rams, trying for their first 2-1 start since 2006, had just 18 yards total offence in the first half compared to 96 for Murray alone. The Cowboys had 202 yards before halftime. Romo, who had 217 yards passing, went 2 yards to Dez Bryant for the first Dallas score. He had a pair of 24-yarders in the second half to rookie tight end Gavin Escobar and Dwayne Harris, who bounced back from a muff on the game's first punt. When the Rams finally started getting defenders around Murray at the line of scrimmage, Romo found him on the outside for a pair of catches on a drive that ended with a 2-yard run by Murray for a 17-0 lead. Murray, who had 253 yards against the Rams in 2011, went around left end before extending the ball over the goal line right on the pylon, and there was no review. His last 100-yard game was the 2012 opener, and he was coming off a 25-yard performance in a loss at Kansas City. St. Louis avoided the shutout on Bradford's 4-yard pass to Austin Pettis on fourth down late in third quarter after an interception by rookie safety J.J. Wilcox was wiped out by a roughing-the-passer penalty against Jason Hatcher. The Rams had a chance to stay in the game on their next drive, but Bradford threw behind Chris Givens while Givens on fourth down. Dallas scored three plays later for a 31-7 lead when Romo hit Harris in stride in the back of the end zone. Tavon Austin had an 84-yard punt return for a touchdown called back by a holding penalty. The Rams also were penalized for a blind-side block that laid out Dallas" Kyle Wilber, who stayed down for a few minutes before leaving the field on his own.
