None of the Cowboy defenders are getting a lot of snaps. They'll be sitting on the bench drinking Gatorade, watching the Cowboy offense toy with the Giants "Big Bad" defense. The Giant defense is going to get pounded so hard they won't want to come out of the tunnel at halftime.
Elliott and McFadden are going to use the offensive line like a surfer using a tidal wave. The Cowboys will run all night long. That's how you neutralize a defensive line's ability to attack. That's how the Cowboys keep their defense off the field. That's how you bleed out the timeclock.
