Do you think football is rigged?

jake the snake thinks football is rigged. there is a video of youtube how he says sports is just a business. when you really think about it how do you know if nfl refs are being instructed behind closed doors how to officiate a game? kind of like a boss telling you how to do your job. you know that would be something they would never want the fans to know about. so it wouldnt be easy to expose something like that even if that was going on.
