The Dallas Cowboys defensive rebirth has begun, Now they are preparing to get to work to find the best players to put on the field to start the season. New defensive coordinator Dan Quinn knows that for a defense to be successful they must be able to stop the opposing team’s running game since that is the easiest and safest way to get yards if a defense is vulnerable. This unit must be able to get ball carriers on the ground early and often, and for this to happen the Cowboys are going to need to rely on their “big three” along the defensive line to get the job done.
