There's a difference between not getting a prediction right and going full on brain-dead.
Imagine even implying that Zoro is going to fight the 5th or 6th strongest of the opponent crew in an arc where he has more portrayal, build-up and screentime than any other before- arguably matching if not surpassing that of Luffy's in first two acts. In Wano, the land of sword, of all places. After all the things with Enma, Hiyori, Yasui, etc etc etc.
I could go on and on and on about it tbh. But the prediction was about as logical as saying Usopp will never meet Yasopp again, or that Luffy's EoS opponent is Shiryu.
Again, easy to say this in hindsight and insult people about it. There were other Supernova captains around and Zoro wasn't the only focus early on (I'm talking about when this thread was made). Like i said, WsW was being painted as a strong contender/rival for enemies like King and Queen, so it made it "feel" like King/Queen/WsW/Sasaki/Jack were of a more equal standing at the time.
Even I went back and forth on whether Oda would do classic matchups or something different and give Supernova heavier focus before fighting Kaido/Big Mom together.
In fact, reality has that Zoro ISN'T fighting the 2nd strongest villain this arc. Kid/Law are tagging Big Mom currently, so this logic sort of gets thrown out the window anyway. Even going back to Dressrosa, nothing even stated Pica was the 2nd strongest, even due to his Hax power. He went down before Trebol too. There will always be an argument there. Zoro also took out Monet (whom Tashigi finished), and Monet wasn't even the 2nd strongest villain there. Law/Smoker tagged Vergo, and there was heavier importance on that fight than anything Zoro did in Punk Hazard. Hell, Vergo is clearly stronger than Caesar, so Luffy didn't even fight the strongest villain that arc.
You also clearly didn't read my post, because I said Zoro vs WsW at the time was being painted as a warmup by a lot of people who thought he would fight someone at least before helping Luffy tag Kaido. Same goes for the other Supernova
