This and the 4th & 1 in the first half. You need to have a call so that if you are half a yard short you just get to the line and QB sneak before then DL can get set. If they'd done that here they prob get it.
Nagy clearly won't let Foles do that. I sensed Foles wanted to hurry up with the sneak but goddamn Nagy has to go through his laminated list of 600+ plays first.
