They already know Zoro is taking down (or at least fighting) Kaido, a new form of downplay is already happening : "
It will be a team fight so it doesn't matter"
We went from "Zoro vs King will be a tag team fight"
to "Zoro will solo King but he is
never fighting Kaido"
to "Zoro
might wound Kaido but nothing more"
to "Scabbards wounded Kaido so Zoro's feat won't be impressive"
to "It's nothing special, all SN will fight Kaido anyway"
