They are two seperate entities. Self defense is the defensive side of the training. The art of Jiu-Jitsu is a self defense technique. But tournaments were created to test your ground fighting skills and what has happened over the years, things have evolved. The rules have changed. I don’t believe in the rules they have now for the tournaments. There are techniques taught now for sport Jiu-Jitsu that you would not want to do in a street fight. The sport schools are not teaching self defense they are teaching how to win in the tournaments. There are similarities but they are growing apart.
