Yup, literally pockets (as in pants) and sacks (as in paper) have the same concept, to hold, carry or protect something. In football, if your pocket is being crumpled like a paper sack from all sides, there is no escape, it is no different than a paper sack that explodes when smashed between 2 hands. The best fix I see is run, run, and run again. Yeah, fans will whine, wins of 10-3, 7-3 and 17-10 will litter our W column, but at least they'll be in the W's. That's the best fix I can think of short of kidnapping a RT and LG from another team.
