Usually a major selling point of BJJ is that most fights end up on the ground, so defend yourself with some BJJ! It seems like if a person gets trained in some art, fighting system, etc. to the point that the person becomes proficient in the basics I listed above that BJJ would be more of an "if" it happens you go to the ground instead of "when" you go to the ground.
Oh and not meaning this to turn into people practicing BJJ for love of the art vs self-defense vs sport.
actually it was Gracie Jiu Jitsu that claimed it.
something like 95% of street fights end up on the ground.
It is not like I am gonna go in the streets and take stats on a friday night outside the night clubs.
Basically, back in 94 everyone was happy doing karate chops in the air hoping that one strike would ko your opponent.
Until this skinny dude chocked out those dudes in no hold barred fights held in a cage.
