How much groundfighting skill is needed to survive on the street? Do you need to be a BJJ blackbelt? Does groundfighting change radically when you include dirty strikes? What about variables such as multiple attackers or weapons etc? I would be interested in answers from those more experienced than I. Personally - I do MMA and I have learned groundfighting. But I don't think going to ground on purpose is the best idea. Its wise however to be able to survive the ground. I think also on the street, escapes and strikes are just as important than submissions.
