Z tego wynika ze tylko QB słyszy zagrywkii.What does the green dot on the back of the quarterback's helmet mean?
The green dot signifies a helmet with a communication device for receiving plays from the sideline. Only quarterbacks may wear them, and only one player with such a helmet may be on the field at a given time. A backup quarterback entering the game while the starting quarterback remains on the field must wear an alternate helmet without a radio device.

Jak ktoś znajdzie cos dokładniejszego niech poda link ???? ."Quarterback coaches or offensive coordinators on the sidelines talk to the quarterback with a radio, giving him specific plays and options."
