1. I always wondered why the punting team didn't tell one of its linemen to intentionally false start, rather than just having the punter stand there without any urgency to get the ball snapped. When the punter just stands there and is obviously not trying to get the ball snapped, everybody in the stadium knows that the punting team wants the 5 yard penalty. If you have an O-lineman false start, look disgusted with himself or better yet point at a D-lineman, and get yelled at by a coach, maybe the receiving team accepts the penalty.
2. I also wonder why coaches don't have the punter commit the obvious delay of game penalty, wait for the receiving team to predictably decline it, and THEN run a fake punt. Seems like it would increase the deception about your intentions to fake the punt with very little chance that the 5 yards would be walked off before the fake.
