what if there is no evidence that S. Nagamine actually wrote anything about Tegumi?
He doesn't mention tegumi his whole life, then after his death in 2000, suddenly we see a chapter devoted to it? I'm thinking: show me the 1986 Japanese version of the book first before I unconditionally believe that one.
The timing of GJJ/BJJ. The timing of an admittedly resurected and defunct term of a dead practice in order to name compiled grappling drills. The timing of Nagamine suddenly having alot to say on the subject of tegumi, after his death. The need for Karateka to have history as oppossed to crosstraining.
Tegumi: the term and Nagamine's words, were raised from the dead to first create a 'movement' then create a product which was popular for the grappling times, while at the same time making it palateable for the traditionalists by not calling it crosstraining and instead establishing it's history thru (perhaps) liberal translation of Nagamine's estate. Then all the subsequent unchallenged references to the book, branching out from there.
A couple things about us Karateka: we like to believe at one time, 'it was all there'. That way we can keep pride with the newcomers on the block like MMA's. heck back when Judo was popular, it sounds like Karateka were crosstraining that as well. Now we are comfortable with saying the sportive judo throws 'were always there'. not quite. Some throws similar to Judo's illegal throws can be found in kata. but the tactic is quite different - it's not who falls first, but who falls hardest. When's the last time you saw a Judoka purposely train aiming a throw so the opponent slams into a wall upside down on their neck? before that, Te crosstrained with CMA's.
Thats what karate has been, an ever-changing, ever-crosstrained art... based on the contemporary trends and needs at the time. Which again is great, but just don't try to sell me that a Karate version of GJJ is an ancient lost secret Ryukyuan Art. sounds rediculously dumb. If it was 'always there' then it was never lost...if it was 'secret' then it wouldn't be a DVD on amazon.com for $49.95.

hasn't karate as an Art grown up enough and comfortable enough with itself that it's practitioners can say without shyness that they crosstrain in a grappling Art like JJ without having to feel the need to cover it with a historical term? alternatively, why wouldn't people feel just as comfortable NOT including groundfighting if they choose a different strategy for the Art's interpretation?
The irony of the position is people developing the most modern systems of Karate today via crosstraining, while trying to use the oldest sounding names and establishing links to the past in hopes of veiling the direct links to the present influences. enough is enough.
am I delusional? am I outta-line?
