Good film review but I disagree with the statement he made near the end about the tight-end. The tight-end is expected to wall-off the defender, not drive him back.
On that play, Peters was supposed drive back his defender but he tried to run forward and wall-off at 90 degrees like he did with the first Pollard run.
However, on the first Pollard run with Peters in it was Tyler Smith who was blocking the defender to the left, not a tight-end, and Smith being a tackle was capable of driving him back.
On that play, because the tight-end was blocking out, Peters should have just driven straight ahead on the Giants player and let Pollard navigate the lane and shift outside.
To be clear, that's not a criticism of Peters because he has not had a lot of time to prepare in the Cowboys' offense, especially at guard. It is a play that I am sure he will get right as he gets more snaps.
