I watched Hiro 's video, and 2 things hit me.
The first is that so many of Ao 's bouts were brutal, he fell badly even off the dohyo so many times, I feel like it's a miracle he didn't get injured and accomplished what he accomplished.
(The second one is technically not about him but I will mention it anyway - in the Onosato/Kotozakura bout, maybe because of the angle of the shot, I swear it looks like the yokozuna puts the ozeki 's hand on his mawashi, and seconds later he loses, so weird.)
