No, but I think it has a lot to do with judo's competition mindset. Judo is in a similar quandry that top-level BJJ players had in the 90s: competition BJJ at that time, from what I could tell, was dominated with points fighting, which was all fine and dandy until they came to MMA and started getting punched in the face. Look at the majority of Carlson Gracie's BJJ champs: Amaury Bitteti, for example, arguably had some of the best BJJ credentials in the world, but couldn't figure out how to transition between BJJ and MMA. Judo has similar issues with turtling/stalling on the ground. Miss a throw? Stall until you can stand back up. Try that in MMA and you get pounded out. Try that in submission grappling and you get back-mounted and RNCd by some BJJ bluebelt. Now with their new ground-unfriendly rules changes, I fear Judo will be relegated to the same ghetto TaeKwonDo has been exiled to. It's not that Judo isn't theoretically sound in MMA, especially in the clinch game. Karo Parisyan exhibited outstanding clinch judo in his prime. I don't think it's a coincidence that RR trains at Karo's old gym and is able to better integrate judo and MMA than most others.
