Who is the "greatest American Taekwondo athlete of all time" is a matter of opinion. There have been many outstanding competitors over the years in different weight classes, different regions of the country, and competing in different circuits or tournaments hosted by varying organizations. There is no way to rightfully quantify who is the "greatest," although many people have their favorites.
The same holds true for expert Masters who teach the art. There have been many, many "great" ones, but there is no way to put one above the other, and a genuine Taekwondo Master would decline such a designation.
