Every academy has one. There is always a guy who is usually quiet and humble that has the ability to "represent" and the reputation of being a "monster." The guy that "regulates" everyone who is not in check, including newbies, and visiting advanced grapplers. Sometimes these guys don't enter contests but some are champions. This is the guy that all the students are asking the instructor questions about in class. So and so does this, what should I do? Most people in the community have "heard" about so and so. Every academy has its top dog; who is top dog in your academy?
