good point Don. Otherwise we could claim Aikido has BJJ based on those pics of O'Sensei choking.
I just say Aikido has chokes...
I will agree that tactics and strategies have caused a divergence. I will clarify my point in that Helio Gracie invented nothing new. He is a great jujutsuka, but Rorion claims that his father changed and modified the techniques into something new. All of the techniques in the original syllabus of Gracie Jiu Jitsu can be found in judo, although not necessarily in the syllabus of the Kodokan.
The fact is, Kano took the strength out of Jujutsu in formulating Judo, so all techniques were based on leverage, and Maximum Efficiency with Minimum Effort, not Helio Gracie. I will reiterate that Helio Gracie is a great martial artist.
Indead MMA and UFC has changed the way these techniques are used in the ring or octagon.
