Ron: What's With the Green Dot?

Our pal Ron checks in to ask what the green dot on the back of the helmets is.

It's to show that they purchased the helmet. Clearly, they forgot to remove them prior to the game. Preseason means fine tuning.

Actually, it's to show which players have helmet-to-sideline communication via wireless communication. (Of course, it's wireless, Tom, what do you think they're going to do, run around with an extension cord all night?)

It's not that fashionable though, is it?
