most people i know that do BJJ do it for sport. they aren't there to learn "self defense" hell most people i know haven't needed to learn to deal with defending themselves since the playground in grade school. the ones that want to learn to fight cross train in a striking art too. usually either san da, muay thai or boxing. and while ppl poo poo on the idea of learning grappling it is a sad sight to see a competent stand up fighter get his ass handed to him bc he ends up on the ground and doesnt know what to do. i have been studying chinese martial arts for a few years and they have a woeful lack of ground techniques. something about it being undignified to roll on the ground like a dog. but if they ever end up there most of them will have a very tough time of it.

as for the multiple attacker situation. thats never a fight you want to be in whether you are a ground fighter or a stand up fighter unless you study glock fu. the truth is the best technique against multiple opponents is to get away from them. even though most schools will train multiple attackers they rarely have you spar with multiple people in a full contact situation.
