Well, as I understand it, Kakuryu met the YDC's ultimatum with his performance at Hatsu, albeit not exceptionally. I'm sure anyone at the dinner table could have suggested that his participation in Haru would be a greater benefit to Sumo (overall) than the potential career harm of under-performance (or non-completion).
Sure, it's pressure... but putting aside the prospect of worsening injuries, it's kind of compelling.
I mean: we have three "active" Yokozuna. Everyone involved would like at least one to show up.
