its a new rule this year. any helmet with a microphone in it for someone to feed the plays to that player must have a green dot on it. this rule is meant to prevent teams from calling fake field goals on the fly. last year that happened a couple times where the holder on the field goal was told to pull up and throw or run at the last second because of something the coaches now saw. this gave them an "unfair advantage" in the eyes of the NFL.
What is it?
