Shelly Ann is indeed the greatest woman sprinter ever but if any one were to say that she has not broken the world record it is a foolish statement. Because every one knows and acknowledges that Florence Joyner Griffith who set the world records in both 100 and 200 meters did sousing performance enhancing drugs not detected because of the inability of the then laboratories. They should at-least stop talking of those records if they can not condemn them outright. Yes there is no doubt that Usain Bolt is the greatest ever athlete and neither Djokovich nor Messi can come anywhere near him.
