I've sparred with a bunch of Kyokushin black belts under MMA rules. One of them even had amateur boxing matches. Some had fought amateur MMA matches.
There wasn't a thing different between them. If they had head movement, it was robotic and easy to see. They'd eat shots on purpose to show that they were manly. I'm not fooled by that kind of stupid shit so I'd make a point of hitting them in the same spots over and over. One dude I kept kneeing in the gut. Another I leg kicked over and over. Another was much shorter and smaller than me so I just jabbed him in the face the whole round. I was in a pissed mood whenever I saw any of those people because they were always doing something fucked up (beating the shit out of a weakling, screaming at someone to do a hand stand when they can't do pushups).
They sure are tough, but that's the only good thing I have to say about them.
People who do Shotokan learn how to move in and out fast and protect their head. Maybe they don't use a lot of head movement, but they can keep their hands up and use decent positioning. They can kick hard as fuck. Their only problem is that they respect the hits too much from all that light sparring and often don't realize they are learning to hit from a little too far away to do damage. A couple months of full contact KB with a good coach and they'll learn to dig those kicks in and work the jab. I have had the shit kicked out of me by dudes that do Shotokan who really weren't anything special, other than having been through the ringer at an MMA gym. I just wasn't good enough to hit them back and got lit up.
They are always respectful, know how to exercise, quickly gain a realistic understanding of damage unclouded by macho bullshit, and are hard to damage without clinch fighting (which they can learn because they haven't been trained in bad habits like above).
If I were to take Sherdog up in my hands like a sponge and squeeze out all the stupid bullshit bro science and the just bleed attitude and distill it into a gym where the philosophy is to never back down from shots to the face, and I think you'd have the average Kyokushin gym.
