I don't know if
@DOTA was getting at this but I actually think he'd be better off doing that again. I think Logan Paul fans would be more interested in a fight with another youtuber or some other celeb, Mayweather fans a retired boxer or another kind of fighter like the McGregor one. That way the opponents would be more to familiar to their respective fanbases and they'd be more hyped up for it.
I think this will make money though.
I don't know, Logan Paul v Pewdiepie would sell better I reckon. Maybe Mayweather could fight Anderson Silva or something.
