Roger Gracie finished his opponent with an X-Choke. A begginer move used perfectly, Roger is the best in the sport.
The issue of whether or not BJJ(Brazilian Jiu-Jitsu) should be an Olympic sport is a matter of some debate. The 2016 Olympics are taking place in Rio de Janeiro the birth place of Gracie Jiu-Jitsu, which was created in the late 1930s. The sport quickly spread becoming so immensely popular throughout Brazil, that when its creator, Helio Gracie, was arrested the president had him pardoned. The main reason the sport spread was the popular Gracie challenge, which was Vale Tudo( anything goes in Portuguese) competition. The Gracie family was almost unbeatable and dominated the fight scene for almost a century. Currently the sport is very popular among the upper class of Brazil's society. They are also the reason the UFC( Ultimate Fighting Championship) was created in 1993. Today Helio's desendants( such as Renzo and Royce Gracie) compete and win.
The main reason that Brazilian Jiu-Jitsu is not in the Olympics is its extreme depth and how difficult it is for an viewer that hasn't trained to understand what is going on. The people who train in Brazilian Jiu-Jitsucan appreciate the subtle hand positioning and the importance of something like an X-Guard sweep or a guard pass. This sport is very difficult to truly appreciate unless you have trained for at least three months, and even then you will only understand the gist of what is happening. However, since the Olympics is in Rio, the birth place of BJJ, many of the people there will understand it. Jiu-Jitsu is very common and almost all citizens of Rio understand at least the basics of it.
