The play we are discussing is at 8:29
This is a zone coverage. Zone blitz actually. They had Campbell follow Lambs motion (Z MO) and then peel off on a blitz. This caused Prescott to try and hit Lamb on the hot route. The Packers had Savage up in the zone cover and he picked him clean. A great bait job on the Cowboys by the Pack D.
