In a few radio interviews, Matt mentions how some people have accused him of exaggerating Bruce Lee's skills as a martial artist and/or fighter. IMO, by leaving Lee's training history with Louis Delgado out of his book, Matt actually undersold Lee's impressive skill set. Delgado was the last point fighter to defeat Chuck Norris and even though Norris defeated Delgado in a rematch, Delgado was still able to break Norris' jaw with a heel hook kick.
Delgado was present in a good portion of Bruce Lee's backyard videos and he told Black Belt Magazine that sparring with Bruce was a humbling experience. In 1974, Delgado told Fighting Stars Magazine that Lee was the toughest fighter he ever faced. This comes from a man who competed against Joe Lewis and Chuck Norris in point tournaments.
Speaking of Joe Lewis, I e-mailed him in 2010, and asked him to expand upon his opinion that Bruce Lee was not a fighter because he had no point or full contact record. I reminded him of his opinion that point fighting was a "game of tag" and that Bruce had left for Hong Kong shortly after Lewis had given birth to full contact/sport of kickboxing.
I also pointed out that despite his references to point karate being a "game of tag," he considered Chuck Norris to be a fighter due to the fact that he engaged in point fighting tournaments. I ended this commentary by reminding him of Bruce Lee's sparring history with Louis Delgado. Joe responded to my e-mail by simply stating that "Louis was not a great fighter," and repeating his mantra that if you didn't compete on the mat or in the ring, you couldn't be classified as a fighter.
