If you really want to see Zoro downplay, just compare the comments and threads after Luffy got adcoc to the comments and threads after Zoro got adcoc. You'll notice that Adcoc started getting downplayed or straight irrelevant in Zoro's matchups the moment he got it. Some even believe that he can't use adcoc for more than 2 minutes lol
King was downplayed the moment he was matched with Zoro
Hakai was downplayed after Zoro blocked it.
Kamazou was downplayed when he got downed by Zoro. But then got even more downplayed when we found out he was actually Killer
Pica was downplayed after Zoro defeated him yet Vergo was hyped after Law defeated him
The list goes on and on
