Assuming Champ Bailey is out of the lineup again, Dominique Rodgers-Cromartie will be relied upon heavily in this game.
That is a role he has taken well to this season.
With Bailey sidelined for the first four games, Rodgers-Cromartie has stepped up and played very well in his absence, matching up against the opposition's best receiver.
Rodgers-Cromartie has one interception and five passes defensed so far. Against Dallas, he will face his stiffest test to date.
Dez Bryant is easily the biggest playmaker the Cowboys have and he can hurt you in a number of ways.
On the season, 19 of Bryant's 23 receptions have resulted in a first down. He also has caught four touchdowns.
Dallas quarterback Tony Romo will look Bryant's way often, so Rodgers-Cromartie must be prepared.
