NFL QB Question

[Central Bassman]

What is with the green dots on the back of all the quarterback helmets???

[fadal]

What I heard it is to tell the refs that they are the only ones that should have electronics in there helmet. I guess its cheating to have anyone one else with electronics in there helmet.

Yep, it's the QB's helmet cause they have the radio. If they see two helmets out there with dots they get a penelty.

thanks...

they are also not allowed to use them on kicks, even if your qb is the holder.

they should give the defense a radio too. why can the offense call plays over a radio but not the d?
