Mayweather to Canelo: 'I fought Cotto and Hatton, not their brothers'

Every so often, Floyd Mayweather gets in one really good, stinging line. Today, he nailed one, as he slammed Canelo Alvarez's previous level of opposition, and said he doesn't compare favorably to Miguel Cotto, a fighter Mayweather beat in 2012.

"I'm not Miguel Cotto's brother. I just look at certain things. I fight Ricky Hatton, I don't fight Ricky Hatton's brother. I fight Miguel Cotto, I don't fight Miguel Cotto's brother. That kid [Josesito] Lopez, he let him get off on him with crazy shots. People can believe what they want to believe. Is he tough like Cotto? No. Can he box like Cotto? No. Can he punch like Cotto? No. Has he fought fighters, faced the same opposition that Cotto faced? No. Am I worried? Absolutely not."

Mayweather (44-0, 26 KO) of course beat Cotto in 2012 and Ricky Hatton in 2007, while Alvarez beat Jose Cotto in 2010 and Matthew Hatton in 2011.

And while Floyd's scouting report is mostly hard to argue, there are two things he may be wrong about. Canelo (42-0-1, 30 KO) may be a bigger puncher than Cotto, particularly at this weight, and he might also be tougher than Cotto, who is certainly tough, but is also a guy who has been beaten into submission before by Antonio Margarito and more or less by Manny Pacquiao, too.

Do you think Mayweather may be slightly underestimating Alvarez?
