You don't get a blackbelt in the first place if your submissions are half assed. He prefers to punch their face in I don't blame him, it's a lot safer than going for a submission and risk being swept.
He doesn't punch either...at least not anymore!!
He tackles you down and then knees you in the ribs until you can't breathe.
YOU, yourself, can get a black belt as well if you wanted one, getting a BJJ black belt is an academic process.
My Brazillian neighbor's brother is a black belt in Jiu Jitsu -- does that automatically mean that he'll e submitting UFC light heavyweights soon?
