Just The Facts : How was the football huddle invented?

The huddle in the game of football is a super important part of the game.  That's where Russell Wilson comes up with all of the great plays (Go Hawks!)  It's very important for the quarterback to let his team know what kind of play he wants to run.  You probably never really thought about how the huddle was invented, because like all of us, you probably just accepted it as part of the game.  Well that's what I'm here for.  Useless knowledge!
