I am posting this new topic in response to this post made in another topic about how long it takes to get a black belt in BJJ. I didn't want to derail that discussion with my question. This is the quote I'm wondering about:
It doesn't matter how many years it takes to become a BJJ BB. The ONLY thing that counts is can you back up the belt your wearing.
What the f*** good is a black belt if you are getting your ass handed to you by purple belts. BJJ isn't like karadee, you can't hide behind your belt. If you cant back your s*** up the belt is worthless no matter how quick or long it took you to get it.
I'm relatively new to BJJ. If what you are stating is true in regards to backing up your belt does that mean there are demotions in BJJ?
I know a guy that was a purple belt years ago, he stopped for several years, and when he came back to BJJ and to a new school he was essentially demoted to blue belt. BJJ had evolved a little since he stopped and started again and his instructor after evaluating him put him at a blue belt level with a couple of stripes even though years ago another BJJ black belt evaluated him at purple belt. Is that the norm or the exception? Can Helio Gracie physically back up his rank to a 20-something year old BJJ blue belt? I would doubt it.
I am being sincere in my questions. I have a brown belt in Judo and my instructor is an 8th Dan and I'm pretty sure I could throw him at his old age. In Judo there are no demotions even though many of the old guys, including the 3 living Kodokan ranked 10th Dan's, can't physically back up their belts.
I completely agree with you that BJJ (and Judo) is not like karoddy in the sense that with karoddy (in many styles) you can kick/punch in the air and kata your way to a black belt. But there comes a point where a BJJ black belt's skills will diminish with age and I personally would not say that their belt or ranking is worthless once that happens.
I would like to hear other people's opinions on this.
