Hey willy,
have you ever fought someone in the streets whom out weighed you by 50-70 pounds...
I do I little brazilian jujitsu, and I have been doing japanese jujitsu for 21/2 years. it involves control, breaks, strikes, subimission, throws etc... and I'm also getting ready to do kempo and boxing.
brazilian jujitsu is only good for the ring!!! if someone comes at you with a knife, are you going to grapple him to the ground?? what if it's more than one guy??? you're going to take him to the ground. while the other guys measures have far his going to kick your head???
about a couple of weeks ago my friend decided to fight two bouncers at a bar... he does BJ. I'm being held back by two 300 pounders inside the bar. I just kept my cool. I wasn't looking to get arrested, I had to go to work the next day. i was able to watch through the window. He decided to take one guy down with him and grapple him. the other bouncer came from behind I started to pund his head in. I would have just choked him out if I was the bouncer. anyway... what my friend did was not a good move....
bc, I kept my cool the bouncers let me leave the bar through the front and I wen t aound the back of bar to get my friend that was catching a beating. by now I could see the cop cars coming and even though my friend was getting fucked up they were going to arrest him on top of that. to make a long story short after that night he realized that he was not the bad motherfo he thought he was in class!!
I'm not knocking brazilian jujitsu. I actually love it. but don't tell me you are taking care of 230pounders or whatever. I'm not saying you can't handle a much heavier guy in class. trust me when I firt started I was getting my ass handled by 16year olds!! the kid weigh 130 I was 180 at the time. it makes you think and it put you in perspective. I learned the "leave the ego at the door" pretty quick.
well good luck with your training!!!
