He's got some strange problem with those flying knees. I guess because he's looking for the takedown all the time, he subconsciously leans forward.
To be fair, this right here is a deceptive, perfectly timed double flying knee. He had the feint knee mostly blocked and that left just came up out of nowhere. High level stuff.
It was beautiful technically. Real high level stuff. But I think tonights flying knee was even MORE BRUTAL and DEVASTATING.
