In all fairness, those guys and women are the top fighters in the top Enshin competition, so they’re not exactly the average karateka from Enshin. I’ve got a bit of a man crush on Enshin though. They seem to have long and close range covered quite well, and what they’re doing seems to be realistic and not leaving much to the imagination. They cover ground fighting too, but it’s not to the BJJ extent and it’s not within the competition rules. It’s basically get the opponent off their feet and stay on yours by either striking, sweeping, or throwing. I’d imagine the ground fighting approach is initiate a choke or joint lock as quickly as possible and get back out rather than an all-out Jiu-Jitsu match.
