I think there are a lot of people who would like to see Hakuho falter, to see him give up something of his dominant position. The bar is set so high that simply not winning this basho would provide hope to those people. I am not one of them, I want him to win this basho and prove, yet again, that he is still The Man. If he can do it without the slapping and arm bars, so much the better.
As to his being chubby, he is listed at 156 kilos, isn't that his normal weight?
