My point is that contact fighting was already around in a Martial Art. Karate and Kung-Fu did non-contact sparring. Lee was credited for creating a contact karate style basically. That wasn't anything new. World War 2 military trainers such as William Fairbairn, Rex Applegate and others devised close-quaters hand-to-hand fighting systems that used anything that worked.
