Amazing ability.
I wonder what the future is at the top level for anyone who practises grappling in a more orthodox manner including a game based around the RG and Half Guard?
It looks like a completely different form of grappling with no orthodox or frontal attack to defend.
Instead there appears to be engagement by leg entanglement and taking the back by Berimbolo type sweeps (includng elements of 50/50 and I noticed the Truck).
It looks as if you would have a very hard time in competition against that type of offence if not regularly employed at your gym.
