it looks like these fellas have a good idea. when they go to the ground, it looks like they all have some idea what to be doing, you can see that they attempt things like side control, and a few throws. the fights are kept standing up, but each one knows "fighting" as a package, in one way or another.

More like easy controlled sparring. Bit unrealistic.
If I can find the video I refer to again I will post it.
