Ok, I'll buy that, even though it's extremely technical. I believe if the defense calls out the snap count of the offense, they have committed a disconcerting "act." Any way, Do you not consider the clap to be parallel to calling for the snap verbally? Because that's what I see, both on Friday night and Saturday. If there is a correlation between those "acts" or word/act, then to penalize A for faking the snap simply because he claps his hands would be the same as penalizing A simply for faking the snap by cadence. Would you agree with that? I do agree that if A is excessively animated in his call for the snap, whether by voice or action, it could be construed a false start.
I also happen to disagree with the "if he hasn't done it all night, then it's a foul" argument. Teams routinely vary the snap count, both in cadence and "actions." We have teams around here who will go on a silent count for 5-6 downs, then all of a sudden call for the snap by clap. Just because he calls for it in a different way doesn't mean the first way is bad, or vise versa.
