I know that there are a million "what-if" questions out there, but this question seems the most practical when applying it to a street fight/self defense scenario. What if you're facing more than one opponent and your main fighting style is jiu jitsu? Jiu Jitsu does teach some striking, but i don't think that it is enough to say that one could be profficient at standing up and fighting. In a fight, if a jiu jitsu practitioner were to take someone to the ground, there is a high risk that one of the opponents "buddies" could easily capitalize on this and attack also. So what is the best method for dealing with multiple enemies when running or talking it out aren't options.
