This article made me remember some Sumo shenanigans. Basically Sumo everyone is very heavy because there is no weight class system, when a guy became Yokozuna while NOT being fat, others complained, and the organization had to point out to the bothers that there are no rules saying you must be heavy... so if you can win while being light, that is not an issue. Other one is a Yokozuna that got infamous for winning a lot by doing cheap moves, he looked more like he was fighting Muay Thai than sumo, often winning by elboing opponents or dodging and letting them fall on their own. Since Yokozuna not only is a title but a job with specific requeriments (Yokozuna are people with the job of showing off sumo in public appearances when the Emperor of Japan is present), the guy got a warning that if he kept winning his fights with this boring style (because his fights often would last 3 seconds or so...) he would get punished.
