Some say the skill level between a brown belt and black belt is indiscernible in jiu-jitsu. I would agree that in some cases, perhaps, that may be true. But, I have to point out that for the most part there is a huge disparity in skill between the elite competitive brown belts and the elite competitive black belts. Some brown belts, have closed that gap seemingly over night.
And so, I have decided to add another post to keep us all updated on the top brown belts to watch out for based on ibjjf rankings.
