I mentioned this very topic myself immediately after the game:
I do like what the Cowboys had at defensive tackle with Terrell McClain and Maliek Collins, they gave a nice push up the middle and did a nice job against the run in the 2nd half. This may be the combo the Cowboys go with moving forward. Crawford has been a complete bust at the 3-tech. So much so, he was was kicked out to DE where he was able to get a sack. Maybe that woke him up?
