For Example, did you know there is one little detail that will make the difference between hitting a scissors sweep or not?
A lot of people that learn some of these fundamental sweeps like the scissor sweep rule them is ineffective because as they progress and start rolling, they are not able to succeed with them. This is all due to the lack of subtleties in the details.
If you are trying to do a scissor sweep on your opponent, the difference could be inches. If you attempt this sweep and your partners butt is on their heels or near their heels, this means you will never be able to hit the sweep. We are talking inches.
The simple trick to finishing the scissor sweep is to pull your partner on top of you so that their base is directly over you and their lower body is light. Take their butt off their heels. If you do this, you would be surprised to see how easy it is to sweep them
These same principles of inches can be applied to numerous techniques that many people do wrong. Techniques like the arm bar, the bow & arrow choke, the hook sweep, escapes, and so much more.
If you never master the basics, don’t even bother learning anything else, it probably won’t work. Just as a house sits on its foundation, your advanced BJJ moves sit on the foundation of its basics. If the foundation isn’t strong, the house will crumble and your BJJ is the same way.
