Welcome to AT&T Stadium

ARLINGTON, Texas -- Welcome to AT&T Stadium for today’s game between the Dallas Cowboys and St. Louis Rams.

The Cowboys have yet to make the $1.2 billion stadium much of a homefield advantage since it opened in 2009 but have a chance with a victory today to win their first two home games of a season for the first time in the joint.

The opened the regular season with a 36-31 win against the New York Giants.

The running game: So much of the focus this week has been the Cowboys’ lack of a running game. All of the big-wigs involved have said the Cowboys need more balance, but will they go overboard in attempting to pound the run against the Rams?

St. Louis is allowing 330.5 yards per game through the air through two games against the Arizona Cardinals and Atlanta Falcons.

While the Cowboys do need to run the ball more (and better), what they do best is pass the ball. If they get too focused on the run game, they might take themselves out of opportunities for big plays.

Good karma: The last time DeMarco Murray saw the Rams he ran for a franchise-record 253 yards on 25 carries in 2011. And he didn’t even start the game.

Those Rams and these Rams are far different from personnel and coaching, and so are the Cowboys on both fronts.

But there’s no question Murray needs to get going if the Cowboys are ever going to have the balance they preach about so much.

Zeroes across board: The Rams are the only team to not allow a sack through the first two games of the season, which makes Sam Bradford happy.

The Cowboys have seven sacks on two games and have had at least one sack in 20 of their last 21 games. DeMarcus Ware is coming off a two-sack game last week at Kansas City and the Rams will not have starting right tackle Rodger Saffold.

The ref: Carl Cheffers’ crew works today’s game. The last time the Cowboys saw him came in Week 11 of the 2010 season.
