I like the NCAA rule. In a college game last year the following play happened.
K 4-? from about the 20. Ball snapped over punters had and he chases the bouncing ball back towards the goal line. He catches up to the ball at the 3 and kicks it as it is rolling out the back of the EZ. Cuz of the LOD, B gets the ball 1-goal at the 1.5 yard line, score and end up winning the game by 4 points.
