IRVING, Texas — The Dallas Cowboys, coming off their Seattle high, will go in search of a sixth consecutive victory when they face the New York Giants on Sunday at AT&T Stadium.

The Giants (3-3) hope to bounce back after a 27-0 blowout loss to the Philadelphia Eagles. They also lost their top playmaker, wide receiver Victor Cruz, in the game. Even so, the Cowboys (5-1) will not look past the struggling Giants.

Dallas feels good about what it has accomplished and its new-found status as a Super Bowl contender following a road win over the defending Super Bowl champion Seattle Seahawks.

However, the Cowboys are not yet satisfied and have no intention of getting caught up in the hype and hysteria that is taking over the team’s long-suffering fan base. The Cowboys also believe they will able to sustain their edge because their formula for success is based on a gritty, grind-it-out running game that is the best in the league this year.

Running back Demarco Murray leads the league with both 159 carries and 785 rushing yards. He is on pace to shatter NFL’s single-season record for rushing attempts.

The reliance on the team’s massive offensive line and the running game is making life easier for Tony Romo. The quarterback went from the focal point of the attack to second chair as the Cowboys are on pace to have more running plays than pass plays for the first time since 2005, the year before Romo took over as starting quarterback.

“Those guys are playing awfully well, and we have that situation in-house with recognizing guys with game balls and or attaboys,” coach Jason Garrett said. “That unit collectively has played really well. They play well together. They’re jelling. They spend time together. They work hard together. It is a really positive thing for our team.

“Those guys have all responded well to that. They work hard. They work as hard as any group as I’ve ever been around. They are old-school offensive linemen. They don’t say a whole lot. They go out and do their job. They do it the right way.”

The Cowboys’ winning formula in 2014 is a throwback to Cowboys’ Super Bowl teams of the 1990s. The earlier squads were led by a massive offensive line that helped Dallas control the ball and the clock. This year, Murray, Romo are easing the burden on the Cowboys’ defense, which has played the fewest snaps of any unit in the NFL.

“Big, strong offensive line,” Garrett said. “We just made a real commitment to it with the personnel over the last three, four years. That’s how you run the football in this league. The way we want to play, it’s the way we’ve always wanted to play.

“You gravitate toward this style of play as a football team. It helps your quarterback, it helps your receivers, it helps your defense, and it helps everybody. Again, being a physical team and controlling the line of scrimmage, that’s what we got to do.”
