So I never really thought about it much until the game on Friday, but when Clemons fumbled the ball on the two and the ball went into the end zone and then rolled out of bounds, the ball was awarded to the defense per the rules. I guess my main question is what is the purpose of this rule? Why don't they put the ball at the one or the spot of the fumble? If it happens anywhere else on the field beside the other end zone, the team retains possession where the ball goes out of bounds. Why is a fumble so much more costly at the goal line?
