I didn't want to hijack another thread relating to cross training BJJ and Judo so I'm making a new one as it got me thinking. Rhadi Ferguson, a former US Judo Champion and Olympian, BJJ black belt and professional MMA fighter was asked about his opinion on 2012 Olympic champion Kayla Harrison entering MMA the way Ronda Rousey did. He said he thought it was a bad idea as Judo had changed so much since Ronda turned pro. He went on to say that in Ronda's era, she was use to people shooting in on her and having to defend attacks like double legs (morote gari) in Judo competition. Kayla hasn't had to deal with that, so it would be a lot harder for her to transition to MMA. In gi BJJ, breaking grips is an important part of the game. in Judo in 2016, grip breaking is no longer allowed if I understand correctly. The IJF have also recently stated that it's athletes are not allowed to enter other combat sports. It might be far fetched to suggest the IJF changed Judo rules to make it harder for Judoka to cross train other combat sports, but it does seem that Judo is increasingly going down the road of becoming incompatible with other combat sports. Where once Judo may have been an obvious option for a BJJ player wanting to train stand up, Sambo or Wrestling might be more appealing. I know of one international Judo player who actually started off doing BJJ, then cross trained Judo, then became an elite Judo player who competed internationally. I just couldn't see that happening in 2016 because of the way Judo is now. Any thoughts?
