So if we assume for a moment that everything there was correct, I'd still say Bruce was very important. If everything else is his movies and what he wrote, he would still be one of the most important figures in martial arts history, that would still make him a pioneer + a massive influence on a generation of martial artists. I'm not really concerned with how much of a master or pro fighter he was, I care about his impact and influence.
Some posters (not saying you) get really mad at the idea that Bruce Lee wasn't some professional fighter, and through that completely miss the point when it comes to why Bruce was important, and how he was important. Bruce doesn't need to be able to kick my arse in order for me to learn from him + he is the most frequently cited figure I can think of by professional fighters + coaches, Jerome Le Banner, Lucien Carbin, Kenny Floridan, Randy Couture, Andy Ristie etc. I always think it's interesting that sherdoggers seem to be very anti-Bruce Lee, but people who actually make their living involved with combat sports tend to think quite highly of him.
I think of it like this, to the best of our knowledge, most of the history surrounding Cus D'amato is actually stories he fabricated, they were big fish stories told by a sly old man. Even though Cus wasn'ta legendary boxer in of himself - that doesn't make him unimportant for his impact and legacy. I could accept that Bruce himself may not have been a great fighter (though I think it's better to say that it's unclear how good he actually was, Chuck Norris who was a fighter opined that Bruce was better than he was), but he was by no means a joke.
