At the time that Floyd Mayweather fights his opponents

[Ray*]

castillo and corrales at least were better.

I agree because the time that Mayweather fought them he himself wasn't an established as he is now or was a couple of years ago.

yet when other guys do that, people give credit to the guy and say that he ruined those fighters ala Hopkins

True, but i guarantee you that floyd beats guys, but he doesnt ruin them,,,,

hopkins i do think ruined 2 or 3 guys mentally or physically,,,

Jesus Chavez, Diego Corrales, Judah, Carlos Hernandez, Jose Luis Castillo all went on to win lineal titles or Major titles after losses to Mayweather....Hatton also went down and weight and defended his title 2 times....that being said Mayweather usually fights his opponents after big wins or in their prime.

Floyd ruins fighters

Floyd ruins fighters

no he doesnt,,, he beats them but doesnt ruin them,,,

he gave corrales the biggest beaten ever and corrales came back and had great wins,,,,

Hatton was slowing down,,,, he was on top, but aggressive pressure fighters usually have very short peak times,, Not saying hatton was shot,, its a good win for floyd, but i dont think floyd ruined hatton,,, he could have still beaten top guys,,, manny ruined hatton if anything,,, talk about a destruction

Can we say that Canelo is the best fighter he's faced?

when Floyd fought Corrales, many (myself included) thought Corrales would beat him. I can't think of one opponent since that so many thought would beat Floyd (Canelo included)
