Alright so the situation was, Kevin was in a weird spot or something. The cart path rule is were you stand in a position of the cart path were your ball or swing wont be affected by the cart path. But no closer to the hole. So in Kevin's situation the only way to take relief from this was by going too far away from the hole were he wouldn't have a chance of even making it on (par 5). Which could lead to a bogey. So he played the ball as it was which is totally acceptable but in your own choice.
So basically the reward of a free drop wasnt really a "reward".
