Lee Jun Fan by whatever he wants. Sly isn't a fighter, never was. Bruce was a fighter first, actor second. He trained Joe Lewis, Mike Stone and CHUCK NORRIS. He got students by sparring with them first, confounding them, and converting them to his way of thinking. Prior to his death, he abandoned his Wing Chun roots, and was doing boxing, greco roman wrestling and ground fighting. Does this sound familiar. He pioneered full contact sparring when people were playing tag.
