bigot with fetish for footballers getting fingered
It's the biggest money fight ever, but I don't think it's the biggest fight ever. Louis-Schmeling and Ali-Frazier still lead in that regard. But these two are the best fighters of the generation, and still widely regarded (but not unanimously, not in my opinion either) as the two best p4p in the sport right now. It's very similar to Hagler-Leonard IMO, they were both still the best p4p, but Leonard waited until Hagler had passed his peak and slowed down enough for him to beat Hagler.
Boxing isn't as important in the sporting landscape as it was then, either.
Still, I don't know anyone who won't be trying to watch this fight.
