The Cowboys have not run the ball well in the preseason.
Marion Barber has 25 yards on eight carries in preseason and Felix Jones has 15 on six carries. They were a combined six for 17 yards against the Chargers.
Cowboys coach Wade Phillips however says both have played well and he has no concerns about the running game.
"Preseason is not a direct indicator of how you are going to do in the season," Phillips said. "So the things I look at are different than what other people look at. I see the running backs running well. I think we are going to be able to block for them well. Would we like to do in the preseaosn game like the Saints last week and make 198 yards? That would be nice but we haven't done that. I still think the running game is going to be good and those guys are going to be good."
