Most of the reinvention I have seen is crap when compared to actual grappling systems that have been around a long time. I would advise anyone who is interested in becoming good at grappling to train with grapplers in grappling systems. Please train with practitioners of Brazilian Jiujitsu, Judo, Wrestling, Sambo, etc. Learn the proper body mechanics and it will pay of in spades for you!!!
Some people don't neccesarrily want to be good at grappling, per se. They want to strike, and be familiar enough with grappling, that against those not trained in grappling, the can do SOMETHING in ranges where their primary training is inefficient, even if it's mostly getting out/up and back to their comfort zone. (Although, I prefer striking from grappling range than from farther away.) BUT, I would say that don't assume that because you're a top striker, you can just figure out grappling. Get the basics from someone who grapples primarily, who has that background. I can out slappy-slappy a good deal of people, but my grappling know-how isn't worth half of a used toothpick. *Especially* not if it's a yummy mint-flavoured toothpick.
I agree, but it's the fact that it's misleading that gets to me. Some here are talking about trying to interpret their kata as expansively and imaginatively as possible, and I have no problems with that--but don't tell me that Chojun Miyagi cleverly hid the De la Riva guard in Gekisai kata.
I draw a clear distinction between interpretation and exploration. If I'm looking at interpretation, the technique has to look pretty much the same; stance, height, range, movement, and final position. If I'm looking at exploration, I don't view it as something that is actually IN the form. In that case, the form is more of a brainstorm device, like, "ooh here's a way to deal with ____ that I'd never considered! Fun!" Two different beasts, to me.
I wonder about that. What if you had a guy who trained and those arts and the extrapolated on a kata technique to add some grappling to karate. It wouldn't be as good as the specialists, but then again it doesn't need to be. If you could get a karate BB and roll with BJJ blue belts that would be good enough.
Good enough for some things, not for others. For example, it may be good enough to avoid un-trained grappling attempts, or even utilize some grappling against the untrained. It's definitely NOT good enough to not get all tangled up by a real grappler. Depends on what you want. If I wanted to learn grappling, I'd rather have some training from BJJ black belts, than get tapped out by BJJ blue belts.
