"I think you're confusing intellectually knowing and being able to sense ("knowing")."
From your own post:
"Another way to look at it - if you KNOW HOW YOUR ANKLE works, intimately, don't you think that would tell you a little something about how someone elses ankle would work, given that we're all the same design (bar minor variations)?"
No confusion on my part.
As for the butterfly guard, it is a guard designed for endless counters and sweeps. An intimate knowledge of my ankle (or my opponent's ankle) does not help me counter the butterfly guard in any way. IF I don't have knowledge of the techniques involved with the butterfly guard and the accompanying counters, I will still get swept, REGARDLESS of how sensitive I am to my own ankle or his.
If it were as easy as being sensitive to my ankle, then I needn't roll with a partner! I just need to stay home, flex my ankle, study it intimately, flex it some more, and I won't ever get swept from the butterfly guard again!
EUREKA!! I ought to write a book...
"High level grappler's just have more of it that low level ones."
Uh, yes, that's why I posted this thread to begin with: how do high level grapplers develop this attribute. I don't think high level grapplers like Jacare and Roger Gracie are Feldenkrais practitioners.
"Think for a minute of how far advance you can read a white belts movements."
I can read that far advance because white belts are that far behind. It's not a testament to my skill, per se, but more a LACK of skill/sensitivity on their part.
"What you're describing is pattern recognition, which is the ability to read motion by using your body. That's the very definition of awareness, isn't it?"
Not necessarily. Awareness, by my specific definitions, is also having the knowledge AND the ability to counter my opponent's movement.
"in order to be sensitive to your opponent, you have to be sensitive to yourself first."
I have to resoundingly disagree. You don't see grapplers rolling BY THEMSELVES first. They are thrown in with a partner from the get go.
You can't develop sensitivity/awareness in a vacuum, which, from your post above, seems to be what you are advocating.
TTT for the Boa!
