They should return to not helping their teammates gain yardage. Remember this scene? Chuck Mercein said he didn't want to draw a penalty so he threw his arms in the air. I don't mind so much the scrums that happen when say an RB gets held up by the D and then the OL comes in to push the whole pile forward, but the tush push is more rugby than football. Three yards and a pile of players. At this point, what's to prevent two-thirds or a whole drive of only tush pushes?
