Tonight while watching football, we were discussing the green dots on the QB helmets. So I went online looking for the "true" answer for the dot. This is the funniest answer I found.
What are those green dots on the back of NFL football helmets for?
I keep seeing these green stickers on the backs of NFL player's helmets and I don't know what they are for. Anyone know?

It's part of the Quarterbacks new religion. I think its called a Bindi. They think that with that dot they can communicate with higher beings from upstairs.
Incidentally the Saints were unaware of this and the reason Drew Brees was wearing one is because they went into a college type system. He got a sticker for every good play he made.
