problem with that is that the QB and pushers just go over the top of the bodies, on one of the plays I saw the pushers actually grab Hurts legs and help lift him above and slide him forward, it wasn't an exaggerated motion, so it won't be caught. But lifting the player is still a penalty. they just got rid of the pile movement as a penalty in I believe 2006 or 2008. I don't recall what year it was.
