The first key is to pressure Peyton Manning if they have any hopes of slowing down this high powered Bronco offense. The Cowboys did not get enough pressure on San Diego's Philip Rivers last week, and only sacked him once. If that happens again this week, the Cowboys will be hard pressed to win the game.
The second key is to be aggressive on offense. The Broncos have scored 179 points in four games. That's almost 45 points a game. The Cowboys can't be kicking field goals, they have to score touchdowns.
The third key is the match-up between Cowboys cornerback Orlando Scandrick and Broncos wide receiver Wes Welker.
Welker leads the Broncos with six touchdowns catches. That means Scandrick must shut him down.
The Cowboys and Broncos will kick-off at 3:25 on Sunday at AT&T Stadium in Arlington.
