There will be plenty of talk about running back DeMarco Murray before the playoff game between Green Bay and Dallas on Sunday. He certainly seems like the Cowboys' most important weapon after they gave him 392 carries during the regular season, and he seems primed for a big game against a below-average Packers run defense.

But it's very unlikely that Murray will win this game for Dallas with a big performance. No matter how many times the Cowboys give Murray the ball, the modern NFL is still a passing league. And that means winning this game will fall squarely on Tony Romo's shoulders.

This year's Cowboys team is a great example of why even when the best running back in the league is on the field, the passing game is always going to be more efficient and a bigger part of any offensive success. As good as Murray was this season, the Cowboys gained more yardage and had more success when they put the ball in Romo's hands.
