Are you asking because you are unsure?
Yes it does help conceal play calls, but signals are still sent in by hand as well. You can even see it being done in the picture I provided.
Your ignorance of the game is strong.
The signals sent in by hand are minor compared to the past you are just making yourself look more ridiculous please stop.... filming today doesn't give a team the same advantage as in the past.
