people just ignore when Zoro look bad, and only count his good feats when compared to Luffy
his Durability and Speed are inferior to G4 , G4 can fly which can cause problems to Zoro, its yet to be seen if Zoro can handle Snake man AS
hes only impressive compared to luffy in AP and Range
and one of the reasons Oda is gonna make him fight Kaido directly because its gonna be a group fight, where he can be useful to damage Kaido bit mostly because Kaido would also have to deal with other strong fighter at the same time, meaning even if he damage Kaido that wouldn't put him above post TS Luffy, because AP isn't everything
I think Zoro will both defeat King and fight Kaido, but not in this Raid, right now he can't do it, in the second Round and after another Power up he should be able to
