There is actually a BIG difference between the "standard" BJJ taught at say most Gracie schools and self defense BJJ though. I will try to find the video but Rener and Ryron themselves have done more than one video on how there are BIG differences between competition BJJ and "street" BJJ and how even schools with the Gracie logo sometimes only teach the former and not the later.
Rener and Ryron are also selling BJJ belt promotions online and takes 2 hours to explain something with 10 minutes of contents. They are not the final authority of BJJ.
Your analogy also fails for another reason. Wing Chun, as an example, earned it's reputation in street fights and challenge matches in Hong Kong and still does today... BUT here in the US how many instructors do you think teach it as a "street fighting" art and not simply a "competition" art.
Well what you fail at, I would guess, would be your lack of experience in actual fighting in the street and in the ring. Considering the training involved in BJJ to earn the 1st promotion to Blue belt in "competition" BJJ, I would give the huge advantage to the BJJ'er doing very well in a self defense situation vs. mostly untrained, fat people in the street.
In the end though, I don't think anyone is saying "the BJJ/Grppler" guy is always "lonely".
Yes they are. You guys are doing this often with your saying how BJJ won't work vs. multiple opponents. This also tells me that you don't really understand what you're looking at when you see BJJ'er train.
What they are saying is that you need to select you art and, perhaps just as important, your instructor with the idea that you are training for that worst case scenario where you are alone and out numbered. Otherwise what is the point of training for self defense.
But see, the reality though is that most Self Defense type training are usual way lower on the level of training than, say BJJ.
