I understand that you can only have ONE player on the field at any time on each side of the ball. They will be designated with a "green dot". Does that mean some other guys will have two helmets one with communications and one without since Carter nor Klubnik my be on the field for every play? Or do they just have one guy putting on and taking off green dots on the sideline. And if so, how would they be able to control who has communications and who doesn't?
