I will say such a thing cannot be graded because a really good fighter can be killed if he slips or is shot or is knifed from the guy behind the garbage can. As far as Bruce Lee people tend to forget he was a movie star..I feel he is overpromoted since he is dead; and died in his prime, it is easy to get carried away with his skill. I believe there are people that could take hits from him and still keep coming and eventually get him down. I don't mean to sound cold hearted but look at the fact that he is dead, how tough could he have been if he died from something as simple as a allergic reaction to some kind of drug?? A drug that is not known to kill people. LIke I said though street fighting cannot be compared to any sport movie star or UFC event because it is mortal combat. Regards
