1. Mayweather has a way better chin than Hatton or Cotto and he's 10x harder to hit cleanly.

2. Watch Mayweather any other southpaw.

3. Pacquiao didn't stand there against Marquez, who hit him continually with ease. That same Marquez is slower, smaller, and less accurate than Mayweather as was painfully evident in their fight.

4. Larry Merchant is a fucking idiot. When Cotto was coming forward and staying cautious he was beating Manny, when he opened up tried to trade, he was getting beaten up by Manny.[/quote]


Mayweather has a better chin then Cotto? How do we know this? When has Floyds chin really been tested? Floyd like Roy Jones in his prime does not get hit enough to know what his chin is really like.[/quote]

He got hit by the same punch as Cotto did against a far fresher version of Corley, and was far less hurt.
2. He took a clean left hook at the end of 12 rounds against De La Hoya with no problems.
3. He took Judah's power way better than Cotto did, and Judah looked way sharper when he faced Mayweather.
4. Mayweather as champion has been slighly stunned once(against Demarcus Corley). Cotto has been stunned numerous times at 140 and 147(to a lesser degree).

All in all there is no question that Mayweather has a far better chin than Cotto.
