It was more a bit of sea change in philosophy that didn't leave the linemen out to dry. Instead of more max protect to give plays more time to develop, they used checkdowns and got the ball out quickly very early to neutralize the complicated pressure looks. It's as simple as the running back goes to where the pressure comes from and gets the ball in space. The first 2 drives were filled with Singletary catches and runs, a jet sweep, a moss catch a gilliam catch and even Diggs caught one out of the backfield. It opens the intermediate passing game up later because the Patriots adjusted to cover the shorter places and Mackenzie started beating his man.
