Glad you posted that clip. I was just saying the other day on a Go Ju sparring thread that they don't want to come at you with western sport fighting tactics. They want to grab you pull you in With Kumi Waza, club you with Atemi Waza, break your arms with Kensetu Waza and throw you away with basic Tachi Waza....Just like he's demonstrating in that clip. All of the Kensetu Waza are part of the Judo Nage No Kata curriculum that was borrowed from these foundational arts, developed for the Kodokan by Tomiki Sensei at the request of Kano Sensei to preserve those techniques in the Judo setting. When David joined our Judo club, he already had years of that bone calcification training from Dan level Go Ju not even counting the 13 years of service in the USMC. It was an honor and a badge of survival to Randori with him for years and take his Shodan Nage No Kata Ukemi after the three months of training up to his test.
