this stuff can only happen in a controlled environment. never cared for Tae Kwon Do because it's all legs and on the street, fights are much closer and you shouldn't kick above knee/waist level . . . entirely impractical. In a more controlled environment this guy gets an A- for execution. I've been in tournament fighting before and I can tell this guy wants to spin right off the bat.
