In bjj, a lot of people emphasize the basics over fancy new techniques. However, when an elite black belt performs the basics against other elite black belts, what is the main difference compared to when a white belt does it?
I believe that at a certain point, when a grappler is considered "advanced", they are able to perform all techniques with near perfection. The only thing that stops them from landing the moves is getting into the proper position, which leads me to my next point.
Set ups. The elite grapplers are excellent at attacking in chains (making the opponent worried about different moves) to such a high degree that they can land the basic moves as a response.
So in reality, basic moves need complex set ups. Get to drilling!
