Have to focus on LYJ's equipment. How he easily blocks ferociously spinny loops/drives near tablet is actually against physics. Yet also able to execute ultra short and wide loops across the net is another mystery. But his reactions, speed and world's best back hand flicks will keep him at the top ranks for a very long time. To beat him needs to outplay him in all those areas. The Chinese are, no doubt, fully commited to study/explore his style. May be the young LSD can challenge (about the same age) him on speed/reactions.
