WoT: NFL Rules are Unenforceable
American Football is a game based on the advancement of a ball down the field. The position of this ball is spotted by humans based on eyesight. This will never be 100% accurate. Ever. Even upon video review, the spot of the ball can sometimes not be determined.
So, how do you expect officials to determine what is a football move? Or, if the defender got his hand inside the shoulder pads of his opponent, making it a “horse collar” tackle?
It is by a great deal of happenstance that Super Bowls are won.
