Brian Waters getting into a comfort level

IRVING, Texas -- Right guard Brian Waters made his first start for the Cowboys in the loss to the San Diego Chargers last week and is expected to hold onto the job when the Denver Broncos visit AT&T Stadium on Sunday afternoon.

Waters moved into the starting lineup after a two week rotation with Mackenzy Bernadeau.

"I'm feeling alright. I'm alive," Waters said Wednesday. "I''m here until I ain't. I'm going to keep playing football. The conditioning will take care of itself."

Waters was part of an offensive line that allowed three sacks, though one could be attributed to quarterback Tony Romo falling down, and a run game that saw starter DeMarco Murray rush for 70 yards on 14 carries. But the lack of snaps, seven in the third quarter, kept the offense on the field as the Chargers went though a stretch with 20 unanswered points to take over the game.

Waters believes there's room to grow with the offensive line and given the health and inconsistent play of the group during training camp, it seems things are getting better.

"Like everybody else, not good enough," Waters said of the offensive line's play. "You definitely have some positives and have some negatives. If you're honest with yourself you have to remember everybody is a factor in a win and a loss, so every time you don't have a positive play that may have been a play that was a factor in the game. So you got to make sure you are highly critical of yourself."
