BJJ guys are BIG on technique, in my experience. Anybody that thinks waza doesn't hold up under live resistance should roll with some BJJ practitioners. They always have a short, medium and long game in mind.
The good ones do. I am still developing my "game" and it changes over time. Some guys have very superficial or linear games that do not have many branches, sequels, or options.
YOu have to train, train. train wtih kata and with very precise and detailed training to commit the smallest details to muscle memory. you become very efficient and economical in montion and spent energy. You then develop Optoins...and then think two or three moves ahead with all those options stored up and ready to be the answer if you need it.
