D,
One clue in bassai and in other forms is when you see hands moving in different directions. When you see one hand stationary and the other move past or away from it quickly you have the possibility of creating the tight rotation of an object. You have to look at the form as if , when the hands are "fisted" that there is something in the hands rather than just blocking or striking. Just an idea. Think about having an opponant in front of you on his knees facing away from you. If you were nice you could take his back, get you hooks in, slip in a rear naked and put him to sleep. That would be a great option. One the other hand, think about your left hand, thumb facing down, on the back of his head with a handful of hair and your right hand on their chin palm up with a hand full of beard. Then imagine you pull his chin like you are trying to start a 15 years old mower that doesn't have any gas in it.
Keep in mind 14 neck breaks sounds pretty dramatic and like "overkill". If the guy called them 14 "neck cranks" people might not look at the comment as just hyperbole. If you control the head you control the body.
Two weeks ago I was teaching a class with some chokes and neck cranks covered in it. As usual we try to be careful. I also let people apply things on me so I know the are getting it correct. Even though we use restraint I still got jacked up a bit and am having trouble turning my head to the right.
I would absolutely hate to have someone really crank something like that with any malice. Maybe it would be better to use the phrase "excessive force' rather than neck breaks.
