Sorry bud, Hayliks is right. What you're not understanding is the application of technique. Wrestling has as much as technique as BJJ but the application and emphasis is different. A simplistic way to look at it is just go down the list of what wrestling is good at and what BJJ is good at. BJJ has very poor takedowns compared to wrestling.
BTW you know very little if you think BJJ emphasis small joint manipulations. You're thinking aikido.
uhhh... but isn't application of a technique in itself technique? like as in the technique of setting up a specific technique to get the technique that is the technique you originally had in mind
yeah and i think that one emphasis of bjj is joint manipulation
