The average thug or drunk could pull it off?
I said the chances are very low.
There is an exception to every rule. Sure there are some people who might be able to pull it off. But why walk from LA to New York when you can fly?
Also they do it so fast that there isn’t much telegraphing. There isn’t a chance to move in and punch the kidney or do anything.
I apologize if I was unclear and sounded like you could do it during the actual spin motion. I sure as hell couldn’t pull that off. Any twitch of the body is telegraphing. The moment you leave your feet or begin a twisting motion you twitch. All it takes is a very small step forward to take the brunt of the impact off the kick. That is the point I refer to as being vulnerable to a kidney or similair attack. It is after you land. And you better believe if someone is trained to block very quick punches that they will be able to get an arm up in time to deflect the kick from their face.
Also it depends on the kick. A spinning crescent kick either with a jump or grounded is not as powerful as you might think. I have been caught by one before to the side of the head. It stung but did not knock me out and the guy was off balance when he landed. Tell me, if your kick does not have the desired result (ie: knock the fukker out), what are you going to do as a follow up technique? Especially from the position you will most likely land in? You could be a prime candiate for a take down-bullrush-form tackle-side kick-haymaker…posiblities are endless. If you can actually make contact with someone’s head with a spin kick, you sure as hell could have hit 'em in the temple with a phoenix eye or just about any other strike you want.
I won’t get into a game of what ifs. If the technique was so effective I would think most arts would include the technique. I have heard even good TKD fighters say that they wouldn’t try those things in a real fight.
