The Broncos have averaged 44.8 points per game this season and Manning has been virtually unstoppable with 16 touchdown passes and no interceptions.
Taking the air out of the ball will not necessarily be the Cowboys' plan Sunday at AT&T Stadium.
"I have a hard time saying, 'You're job is to keep them off the field,'" coach Jason Garrett said. "I think that's a byproduct of executing ball plays. You don't want to say, 'Here's our objective: we're looking at that clock.' That's not our objective. Our objective is to execute this play so we sustain drives and then score points. It's still about scoring points. If we went out on the first play of every drive and scored a touchdown that would be good."
The Cowboys have averaged 26 points per game, but that includes three defensive touchdowns. Maybe playing at AT&T Stadium will help. The Cowboys averaged 33.5 points in the two home games so far this season, both wins.
"You've got to do things to keep drives alive and take advantage of your opportunities," tight end Jason Witten said. "I don't think you can get outside your system the way you play and play into their hands. You have to trust that and obviously you have a lot of respect in what they're doing as a football team."
