The oline, for all of their size and strength, not only were they getting whipped physically, but the were also clueless on "who" they should be blocking.
They were reminiscent of a Don Mahoney-coached oline, with at least one of them standing around looking for who to block as the JG was getting flushed from the pocket.
JG wasn't helping them with his lead feet, and determination to hold on to the ball as long as possible, but they played poorly, and even if they were getting beat by a stronger Dline, actually having them all block someone on every play would have made a difference.
