even Oda is adding "people say" before he state he's the strongest
it's obvious Oda doesn't want to commit
and based on how Oda is handling this fight, am convinced there's no tiers and ranking in this manga, characters are as strong as the plot demand, the idea that villains whose role will be after Kaido fall will be stronger than him just because could be true
Why is it possible they defeat Mama, but they have no chance to do anything against Kaido?
again Kid being a hype tool is not an option, Oda gave him panel time and was major part in the build up before this fight, I don't care if he didn't do much so far , it's a given he will play a major role against Kaido eventually
