Posts like this (not singling you out!) got me thinking- I felt similarly cheated and disappointed after Hakuhou henka'd Harumafuji for a yusho decider, which I think was a kettei-sen but could have been a honwari day 15 bout.
But then sumo moved on, Hakuhou remained in the picture and I slowly warmed up to him again. With his antics this time around, I doubt he'll be around for long enough to mend his reputation, and I honestly don't think I want him to.
It's just a crying shame that these two days are going to be sitting on the top of the memory pile of such a brilliant rikishi.
