I think he might have been kidding. Sarcastic Type.

Some pretty good answers up there. But what about against an opponent of skill? None of you mentioned it. Thats the cornerstone of JKD. QUESTION IT. Question all of it. That is what makes Jkd what it is. Once you begin to ask the correct questions about your training and even about yourself then that is when you learn your art.

And to my question I answer that the boxing blast has been adopted for use against opponents with good enough defence to avoid the straight blast.
