I don't know how they are expecting Sabo to push Kaido past mid diff without adcoc.
I mean, can Sabo react to a Thunder Bagua? I think we're overestimating him too much just because he fought against someone as weak as Fujitora in Dressrosa. Fujitora is bad at CQC and even called the weak, non-advanced Haki version of Luffy in DR someone "strong".
This causes these guys to lose their rationality when it comes to scaling Sabo, even though Sabo has Adcoc, that's not a guarantee that he will defeat Kaidou. The fun is just starting if he has Acoc...
