God Forbid a beginner hasn't quite learned it yet...
First of all, most of the bitching I've seen has come from more advanced guys who should know better (like the brown belt Goat Meal referred to). In any event, how is it any different than not knowing how to defend an armbar or a triangle and then complaining about getting caught in one?
If people spent half the time learning to defend neck cranks that they spend whining about them, this wouldn't even be an issue.
It's usually bad form to go for a neck crank. I have been neck cranked by my instructor though, so it really depends. If you initiate questionable jiu jitsu, don't cry when the guy tries the same thing on you.
It's all good, I'll be more ready next time.
See, this is the sort of thinking that I just don't get. Why are neck cranks considered "questionable jiu jitsu"? My school teaches them on a regular basis just like any other technique, everybody uses them, and nobody gets injured or complains about them. From what I've read on this forum, this apparently isn't the case at a lot of (and possibly even most) other schools. But why is that?
By the way, I didn't mean to give the impression that my response was directed at you in particular. It's the more experienced guys who look down on neck cranks that I don't understand. The funny thing is that many of them see nothing wrong with using heel hooks, which are far more likely to cause serious injury than a properly applied neck crank.
I am about it being taught.. just to the experienced guys who are very unlikely to "crank it" when rolling. I trust my higer belts. But there are even blue belts that i just straight out say "i don't trust you heel hooking/neck cranking me so don't do it" when we spar.
