I watch a lot of martial arts technical breakdown videos and was struck by some things in the following video, breaking down some facets of Conor McGregor's game, that chime with some of the kata and bunkai concepts Iain (and others) have brought to the fore in recent years. I love seeing these sorts of linked martial arts themes and commonalities.
In particular how he uses his non-hitting hand to set datums (data?), create space, deny the clinch, sense the direction, movement and energy of his opponent, etc, How he hits where his right hand was in order to better target his left hand in the midst of the chaos. Stuff that's very easy to miss when you watch Conor fight and see the more flamboyant kicks, show boating, slick slips and counter lefts.
