The Cowboys drove inside the 20-yard line twice in the first quarter and had to settle for 23- and 32-yard field goals.
They were crucial missed opportunities in a 19-13 loss.
"You can't have three points in the red zone against these teams," Witten said. "We have to be more efficient down there. We know. We just haven't executed it. I don't know anything else to say other than to you have have to put seven points up there. Otherwise what happened tonight is what happens. You let teams stick around and beat you."
In 25 red-zone possessions this season, the Cowboys have 11 touchdowns and 11 field goals.
