For a few plays, the Cowboys looked like they had a legitimate running game against the Falcons.
Felix Jones busted a 15-yard run on the first snap of the second half and followed it with a 6-yard gain. Lance Dunbar ripped off an 18-yard run the next snap. The Cowboys' other 15 carries gained a grand total of 26 yards. That's not nearly good enough.
The Cowboys once again didn't get much push up front, with the interior offensive line particularly struggling. Phillip Tanner, who was jumped on the depth chart by Dunbar, was stuffed on fourth-and-short on his only carry. No wonder Jason Garrett lacks confidence in the running game.
