How many losses should Mayweather have on his record?

[ruthless rocco]

Which other "greats" started their careers at a lower weight than Mayweather and had sucess at middleweight?

I don't know the answer, because I never posted that. But one serious question for you? Obviously you're a big Fan of Floyd's Rocco, my question is , Do you want to see him fight again, and if so, Who against?
the reason I ask this is I don't believe Floyd's fans particularly want to see him fight, I don't think Floyd particularly wants to fight, so why the fuck does everybody try to make these ridiculous match ups?

I'd love to see Floyd fight McGregor.

Floyd is pretty much done with boxing. I believe he's gone on record as saying that he doesn't enjoy the sport, and hasn't for some time. He is however, in the very unusual position to be able to profit from his boxing skill, talent for self promotion, and the current fixation on boxing vs UFC. He can make himself a shit tonne of money by promoting a mega fight against McGregor--a man who has followed Mayweather's blueprint for self promotion.

Now, boxing fans are mad a Floyd for not fighting all the biggest and heaviest fighters, or the current crop of top prospects. But he's not interested in boxing, or pleasing fans. He's put his health and life on the line for over 20 years of professional prize fighting, and now he just wants to make money. He doesn't want to take any more damage to his brain or body simply for your entertainment. He doesn't want to make other men (management, promoters, gamblers, etc...) a bunch of money by being beat up. He just wants to make money. Which is completely sensible -- but so many people have bought into Floyd's "Money" Mayweather persona, that they hate any, and everything he does.

What Floyd understands, and what many many boxing fans don't, is that prize fighting is about money. Fighters fight for money. Not glory, not to have the picture on the green belt, not to have an amazing set of statistics. Money.
