Indeed... and conversely the best fighters are often the ones who don't brag at all and show little to no outward sign that they have any fighting skill. The "Mr. Miyagi" kind of people. ;)
His dubious past aside, Lee rejected the teachings of Wing Chun (and by extension all traditional (or what he called "Classical") martial arts) and founded Jeet Kune Do. Some of Lee's views on martial arts may be described as... questionable. E.g. Bruce Lee believed in no set stances or forms/patterns -- things that are fundamental to many traditional martial arts, including Wing Chun. Oh, and the fact that the practice of set stances and forms has worked quite successfully for centuries/millenia of pre-machine gun warfare. :rolleyes: IMO generations of brutal combat > one guy's published opinion. :p
Heh, yeah, as far as I can tell, Yen's antics were pret-ty tame compared to what Lee got up to. And besides, Yen isn't worshipped as a martial arts god by a lot of people -- he doesn't float around purporting to be some high authority on the subject. ;)
