Mostly Harmless
It's clear that this is a friendly sparring session to the takedown only. It's a terrific example of how solid taichi can be when trained well and performed by an experienced practitioner.I'm judging it on the fact that you had two guys grappling, and one guy wasn't able to stop or counter leg takedowns, something which is fairly elementary in wrestling and grappling in general. It seems bizarre that you would use the excuse that he was training for a competition. Why would you train for a competition that didn't allow leg attacks with a guy who is going to use leg attacks?
I can understand where you're coming from, Hanzou, in that it doesn't seem like the legs were declared off limits for this sparring session and the tai chi guy did seem to have some trouble with that. But, you're drawing some tenuous conclusions.
Personally, I think it's a great thing that he's willing to open up his toolkit and work out with guys like Marcelo Garcia, and while he might not have the experience right now, he's certainly doing the right hting, which is to be willing to expose his weaknesses in order to improve. I have nothing but respect for that.
