The issue with this is TMAs arent like Boxing or MMA, where even local events tend to be televised on local access channels. You can't even find videos of every form or SD drill in any TMA, forget just finding videos of everything Karate has to offer. If you go to youtube and google you're going to find Flashy Demos and Sparring, not much more. Thats what brings in students, or what parents wanna keep record of their child doing, so thats whats getting recorded.
Paul D and K-man both gave examples of uses and the type of grappling taught. Everyones been very clear that it isnt free rolling in the sense of BJJ or Judo, if you're still looking for that you havent been paying attention.
youtube popped up this example, if i had more time Id give more:
I believe Paul D gave another example earlier.
