Have you never wondered why certain players have a green dot on the back of their helmet? In case you didn’t realize it, the dot signifies which helmets are equipped with the speaker system in order for coaches to communicate to a player during the game. When the team is on the field, only one player is allowed to have communications come into their helmet in order for them to relay the information with the rest of the team. On offense, that player is the quarterback. On defense, the responsibility could go to any player. Most importantly, this player needs to be on the field for a majority of the snaps in order to not disrupt the communication system.
