It isn't a bullshit fantasy.
I roll evenly with blue belts and often threaten to tap brown belts. I'm a solid average player. I'm also large and I command enough technical understanding that better people come to me and say, "what do you think about that and how should I do it?"
Guys that I train with, who I outweigh by 100 pounds and have that much on them when it comes to virtually every major lift, are routinely able to escape to their feet by utilizing classic escapes like the elbow knee, free your head from Kesa and uphill turn, by starting early and knowing where they are going, or waiting for me to start an attack from a dominant hold and moving.
Better, if we don't start a round timer and they play safely enough, they will eventually tap me as I start to gas, by evading a submission, scrambling to their feet, and getting on top.
For that matter, a 10 year old who trains for like 2 months will send a fit 12 year old flying with an Upa from mount if he's untrained. That's good self defense.
Yes, if my fat ass 100% gets kesa with elbow control on someone half my size I'll be able to maintain it all day, but how do I get their easily against a small fit man who knows where he is going? All he has to do is endure and escape and it isn't unreasonable.
No one with a brain in their head thinks beating a stronger larger and better trained person is the point. For self defense it is always beating a larger less trained person and that is child's play, because the stuff works.
The other day I saw a 15 year old with 3 months BJJ and 1 year high school wrestling triangle a 30 year old fit man with 80 pounds and twice the strength.
