For instance, how many techniques does a white belt need to have nailed before he's considered ready for his blue?
Can he not be superb at just three techniques and be able to smash most opponents with these techniques to be graded upwards?
Let's say he can't perform a triangle choke no matter how much he trains and practices it. It's just not a technique that comes naturally to him and probably never will. Is this person doomed to a future of never going past white belt?
I'm not talking about belt chasing for the sake of it. I'm asking if there can be more than one way for a BJJ player to progress, or is the road to progression set in stone?
