Here's a quick test for you, grappler. Watch the video below. If you quickly realize that you've already seen it, then you are a huge grappling geek. That's pretty much the end of the test. I think we all know where things stand.
Honestly, I can't figure too much out here. This looks to be some form of teen combat Sambo tournament. The stand-up stuff reminds of old school point fighting Karate. But, it's all about seconds 6 through 8.
Enjoy this. If your here (i.e., at DSTRYR/SG), then it should be right up your alley.
