Stipe Miocic, without a shadow of doubt.
People bash Ferguson for being weird, but Adesanya is ten times the weirdo Ferguson is; however, since people are sheep and listen what the crowd says (in this case, Dana calling Ferguson weird), everyone hopped on to the bandwagon. It's that PR machine: Adesanya became famous because the UFC said he is famous, when it should be the other way around; the UFC should say he is famous because he actually became famous. Because of this, Adesanya will never be a big PPV seller.
Stipe Miocic is just like the Rocky from the movie. His fights are legendary. Him beating Ngannou when everyone thought he was gonna get knocked out in seconds? The way he made a comeback against DC like Rocky in his second fight?
Yeah, he is a legend. No drama either, which is nice, though not necessarily popular with an audience that consists of snowflakes that act like teenagers and never matured. He is basically an old-school man; the epitome of what masculinity has always been portrayed as. Family-driven, hard worker, non-gossiper, provider, etc. If you ever asked about the "American Dream," regardless of whether you consider it real or not, he is the manifestation of such aspiration.
