And professional football some players have microphones in their helmets that allow them to communicate with the coaches on the sideline what does this indicate

A very great question and the answer is yes. in 2003 or 2004 there was apparently cheating was found.  the coach was found giving the football players  cheating advice which they were taken out of the game. so this indicate that helmets should not let them communicate with there coaches. Its just wrong.

To be honest i thinks its between the first answer and the third answer
