The rule allows you to move the ball to a dry spot at yard line
where the play ended, it does not allow you to add yardage to a play just because you think it looks pretty on the field. What if it's close to a first down, you going to move it forward a half yard? Call it what you want, moving the ball and giving yardage not earned is not supported by any rule or mechanic. It is against the rules and is wrong
