Bruce Lee, Arnie, Evil Knievil, all leaders in their day. They laid the foundation in their chosen field for what we have today, and what we have today is so much better, especially in the case of Bruce Lee. We know Bruce cross trained, but we have so much more exposure today of other arts. Those other arts and the associated expert exponents and instructors are much easier to access now. Bruce just pointed the way, he was not the way.
