What's the best argument against FMJ being the greatest?

I'd argue Pacquiao could be ranked higher than Mayweather.

 

A more accurate statement would be that US fighters rarely ever want to travel. Their circumstances are not typically different from non-US fighters.

 

I agree, also why I feel he now deserves to be rated ahead of Holyfield as the greatest ever cruiserweight.

 

Never the best in any division except 135, 140 and 147?

 

Never proved it. Never unified.

 

Their circumstances are very different.

The majority of the biggest TV networks are U.S. based.

The majority of the biggest promoters are U.S. based.

The majority of the world's best fighters are U.S. based.

The majority of their competition is U.S. based.

The majority of the biggest fights are held in venues that are U.S. based.

 

Of all time?

 

This is all over-generalised. The US is the most financially lucrative market for particular fighters in particular weight classes at certain junctures of time. The biggest boxing star in a particular country will often be in a similar situation as the big US fighters - namely that the money keeps them fighting at home.

 

He probably has a case at 140 and 130.

 

Tszyu and Paul Williams for a start.

Judah, Hatton and Cotto were at their best at 140. Floyd had the frame to move up and build muscle and wasn't having tough fights like the other guys v Tszyu etc.

Chose Mitchell and Baldomir over Margarito... It goes on.

 

You have him above Argüello? Achievements wise?

 

The best argument is in order to be the GOAT you have to find another super elite fighter in or around your division. You have to fight him in his prime and then beat that man.

Floyd never did this.

Duran did. So no, Floyd cannot be considered the GOAT.
