Ok, so it popped 7 times and he may be badly hurt. You know what? If he's badly hurt, I think that's stupid. It's not brave, it's stupid and arrogant.
I've heard it said that there is no losing in jiu jitsu. "You either win or you learn." I looked it up and it's attributed to Grand Master Carlos Gracie Sr.
So what's it mean about a dude if he loses 10 years ago, doesn't adapt his style, doesn't learn anything about how to beat the lockdown, doesn't learn anything about how to beat rubber guard...what's it mean if that same guy goes out 10 years later, refuses to tap and gets himself badly hurt?
It's just stubborn.
