Haven't heard of that. Care to elaborate?
Mostly a joke, as you could never do it in a widescale. But Genki Sudo created his own grappling event called Ikkiuchi (One against One, or as he said, I against I). Here are the rules as I remember them from the latest tournament (first one had BJJ point system, but I believe they changed it).
Has to be set at a japanese temple for maximum street fighter II stage effect
5 minute match, but if there's no submission in those five minutes, they restart and do three more minutes
Submission is an instant victory of course
Similar point system to BJJ, but there were bonus points for high amplitude / crowd pleasing throws or other acrobatic maneuvers.
allowed to wear a hakama if you wanted
Stalling strictly enforced, would be stood back up and/or penalized
In the event of a tie, Genki Sudo decided who won based on work ethic/crowd pleasing factor. I also think he could decide against points if the guy just stalled it out. Again, I'm basing this on something I read like two years ago on some clickbait site so I could be totally full of shit.
There was a huge amount of submission victories because of this, tons of throws, shit was cash. I think every competitor put on a great show, and it's one of the few times I've watched grappling matches for fun than to just study the tape.
I guess I'm saying I want every event to be judged by Genki Sudo, where he is the emperor in the colosseum deciding who did the cooler shit, and sentencing stallers to death by lions or something.
