Offensive line pleased with its work

ARLINGTON, Texas -- The Cowboys have rushed 31 times to the left side of the offensive line this season, including 14 times off left tackle, third-most in the NFL.

After Dallas' 31-7 victory over the St. Louis Rams on Sunday, when the Cowboys rushed for 193 yards and one touchdown, plenty of offensive linemen were pleased with their work, but they also understood more work is needed.

"It's all about whatever the defense gives you, and we try to take advantage of it," guard Brian Waters said. "You could have a day like this and people would call it luck or take something away from the defense. That defense is a pretty good group. As an offense, as we continue to move on, it's all about moving the football. We're going to go against some good teams that are better at other things."

What was also important was keeping quarterback Tony Romo from getting knocked around. Romo was sacked just once on Sunday and didn't seem to be under much duress. You could point to Dallas' getting the run game going -- Demarco Murray rushed for a season-high 175 yards -- and getting tight end Jason Witten involved in the offense (five catches for 67 yards), which got the linebackers worried about him rather than the run game.

After the Week 2 loss to Kansas City last Sunday, there were concerns about the offensive line and whether starting Waters would fix things. Mackenzy Bernadeau and Waters played the guard spots to give the Cowboys a different look.

"It was pretty important for us to make a statement and put (the Kansas City game) in the past," left tackle Tyron Smith said.

"They did great," quarterback Tony Romo said of the offensive line. "They created some big holes, and they also gave me time throughout the game to do some different things and get to some certain guys that you normally wouldn't get to."
