Question and opinion. Is it the art form the person takes, the self defense system or the core belief the person has about themselves and their ability to defend that has the real impact.
I have had students with beautiful technique, power, balance and execution who would not survive an attack, and others with much less skill I would never worry about.
Yes there is a combination here, but what carries the most weight in your opinion?
I remember many years ago I was walking with a guy I knew from a boxing club we both went to and his girlfriend. As I recall we were headed to my place to knock a couple back.
This dude was a big boy and talked a big game. Not the best boxer but not the worst either. He believed in his ability to fight, and carried himself with confidence.
So anyway we walked past this pub and there were 4 guys outside smoking. They started making some comments about buddies girl, and of course buddy starts beaking back at them. Next thing you know they had come out to the street, and things got up close and personal. Wed already had a couple drinks, and things quickly escalated.
I just remember one guy swung at me and missed, I swing back and connected, sending the guy stumbling over a curb. Another one grabbed me, and next thing I remember I was on my back, wrestling with a rather large dude. I remember looking sideways to see my companion doing his best Carl Lewis impression, as his girl was calling him a p#ssy and other colorful adjectives.
I managed to get to my feet but not before eating a few kicks to the ribs from one of them, and once I did I managed to connect with a pretty sweet left hook to the guy I was wrestling, causing enough of a gap to beat a hasty retreat from the 3 angry men in front of me. (The fourth had chased after the guy I was with)
The moral? You have no idea how you will react to a situation until it happens, much less how others will.
