We used to have an old guy at work who claimed that the mob controlled most of the NFL teams (owners), and that the games were rigged.
It's always easier to look back and find a pattern that fits random facts and figures. Yet we are talking about human beings, so it's reasonable to believe that tomfoolery does happen on occasion - but also statistically, half of all players, coaches, and refs are below average... just like your coworkers.
So maybe a lot of the odd results in sports can be attributed to people being fallible - I don't think that would be a surprise to anyone. But strange things do happen, mysteries that we can't prove or disprove completely.
I doubt if Chuck Norris controls sports, but he could if he wanted to.
If he was discovered, no one would ever be able to escape and reveal the secret anyway. Remember, if you can see Chuck Norris, he can see you.
