Question

whats the green sticker on the bak of tom brady and brett favre's helmets for?

Answer 1

it's to show that they have radio connection from the sideline, every player ( usually qb's) has to have a sticker if they have the microphone inside their helmet

its a microphone so they dont have to go over to the sideline to get the play

Answer 3

So everyone can know whos talking to who. all qbs have them. its stupid.

Answer 4

it is there for so they can here the play

Answer 5

That’s something new for this year. All QBs will have a green dot on their helmet. It signifies that the player has a radio helmet and the NFL will put the stickers on the helmets themselves each week. Only a QB can have a radio, and only one green dot can be on the field at a time. So, if a 2nd string QB comes in for a trick play, he has to have a different helmet to wear
