Drew Lock had to avoid the big mistake. And he could not do it at a key moment in the second quarter of the Giants’ 27-20 loss to the Cowboys.

Lock set up the Giants’ opening score with a 29-yard run in the first quarter. After Lock was ruled short of the end zone, running back Tyrone Tracy punched in from one yard out to give New York a 7-3 lead. Lock’s day went downhill after that.

Drew Lock put some excitement into the New York Giants' offense on Thanksgiving. The quarterback, replacing a sore and inactive Tommy DeVito, took off on a scramble on the Giants' first drive. It looked like a 30-yard TD run but review dashed that.
