Please excuse my late entry to this thread, and my interference on other's territory, but...
I really enjoyed the video, I know very little about either BJJ or IKF TKD, but from the little I do know, I am guessing that the white uniforms were TKD and the blue uniforms were BJJ (please feel free to correct me if I'm wrong, it wouldn't be the first time) and from what I saw both parties made a reasonable account of themselves "out of their element" so to speak, some of the grapplers did a pretty good job in the stand up stakes and vice-versa.
Like I said, an unqualified opinion from an outsider, but I enjoyed it anyway.
