The problem is that you can't compare him objectively. You obviously love everything about him and this clouds your judgement. Comparitively you probably have limited knowledge in comparison to modern day MMA fighters. There are more effective styles and Bruce Lee never had a chance to compete against them.
The way people talk about Bruce Lee sounds wayyy too much like how your great grandfather would describe some unknown fighter who could beat anyone in the world in his day. I believe it's more myth than legend.
"In my day Joe Boxer beat 100 men in a row, and fought 158 rounds in sweltering 120 degree heat....sonny"
Yes and I'm sure you are extremely knowledgeable and have first hand experience to make a judgment call here. Stop lying to yourself.
