It does make me wonder if that's the reason Hakuho has turned damned near 'lazy villain' these days.
Last night, Hakuho beat the crap out of Yoshikaze (the bloodiest match I can remember seeing) before tossing him into the crowd well after the bout had been won. This was the worst of his string of villainous acts this basho.
Is it his injured elbow? Is he bored? Is he publicly commenting on NSK's "Japanese Yokozuna" match-rigging campaign?
There may be some clue in the fact that the English commentators are unusually frank in criticizing his behavior while pointing out that he has already captured just about every meaningful record in the sport. Perhaps Hakuho is reacting to being forced to retire.
