Cowboys' offensive line playing better

The Cowboys' offensive line produced one of their better all-around games Sunday against the Pittsburgh Steelers' front seven.

Running back DeMarco Murray rushed for 81 yards on just 14 carries. As a unit, the run game picked up 91 yards on 17 carries.

Quarterback Tony Romo was sacked just once and knocked down twice.

"I thought they played one of their best games," coach Jason Garrett said of the offensive line. "I thought Tony was as comfortable in the pocket as he's been in a long, long time. You know, it's hard to block these great rushers in this league and I think for the most part the guys did a really good job of that."

The right tackle rotation between Doug Free and Jermey Parnell is doing well. Garrett said the competition between Free (47 snaps) and Parnell (23 snaps) has resulted in each pushing the other do better.

"I think it's been a real positive impact for not only Doug but also for Jermey," Garrett said. "Bill Callahan has done a great job. That's something he wanted to do a couple of weeks ago just to rotate Jermey in to take some reps in practice and see how it went and he thought it went well. He wanted to rotate a series in ballgames and play it out as the game wore on. Doug has played more than Jermey in each of the last two ballgames but has played some of his best games and Jermey has responded to that challenge also."
