IRVING, Texas -- You don’t give a quarterback a $108 million contract extension to be a bus driver.

But owner and general manager Jerry Jones insists he’ll be pleased if that is his return on investment for Tony Romo’s contract, as long as the Dallas Cowboys keep dominating with the running game.

Romo played a complementary role in Sunday’s win over the Tennessee Titans, when the Cowboys chewed up 220 yards on the ground, with DeMarco Murray doing most of the damage. Romo completed 19 of 29 passes for 176 yards, tying for his fourth-lowest yardage total in a win during his career.

“I’m probably the one that’s standing right behind Tony and saying, ‘Yes, we like seeing that,’” Jones said Tuesday on 105.3 The Fan. “When you can have that balance – and that’s a word that’s overused, balance, and the other day we had more of a lean to the run – we’ll take it. That offensive line played lights out for us, but when you can have more of a balance, which means that you’re not sitting there with a highway show of passes for Romo, then I think we’re seeing you have a better chance for your defense to be more effective, play less plays, better field position. All of it works together.

“So the way that we played Romo the other day fits me just fine and fits him just fine. It’s called winning, and that’s what we’re here for.”
