I apologize for not being more specific.
Rambo's statements made me wonder:
Seatea, would you say that innovation in this particular aspect was also occuring in Japan at the same time?
Specifically, I am referring to the fluid transitions between positions and those things occuring prior to a submission. Taking into account technological limitations of the original video, the part around 3:11 deviates from the "its over at ippon" structure. Some may say that was pure flash for show. I feel its as least as likely that he truly felt that was a viable and accurately-executed technique at that time.
You have to understand that the above video shows jujutsu, not judo, and the standard teaching method for them was kata*. There were plenty of techniques shown that are most likely not viable in real life, and many of the techniques that are viable were badly performed. With judo came regular, safe sparring and competition, where the bad techniques get filtered out, and wrinkles in good ones are ironed out. IMHO jujutsu seemed to 'evolve' by copying the developments of other arts, judo, various wrestling styles etc
As to groundwork, many of the improvements made in Japan came from schools using the Kosen ruleset (the triangle for one), the judo equivalent of scholastic wrestling, which favoured groundwork as a way the reduce injuries. They would have been different to the developments in Brazil due to the ability to win by pin. Many of these skills are still taught by older judo teachers, but they can be hard to find as the IJF started to discourage ne-waza younger coaches/competitors never bothered to learn it as it was unlikely to be anything they could use to win under the IJF rules.
Introducing competition can be a double edged sword as many become solely interested in winning medals (
Brian Jacks, a famous British judoka, admitted to having no particular attachment to judo, it was just what he was best at, and therefore most likely to win in). However, overall the benefits are worth it.
*That's not to say that some jujutsu schools didn't produce good fighters, off the top of my head
Yukio Tani was one such fighter.
Like rape and pillage?
(sorry, couldn't resist. Should take this to war room.)
Rape and pillage was already a time honoured tradition by 1912.
