Mayweather would've had a much tougher time with Clottey.

Floyd would chop Clottey with hooks to the body if he left that area exposed, he's a better body puncher than Pacquiao. Clottey would open up more against Floyd because he doesn't throw those long combinations anymore, but that would be to Mayweathers advantage as he'd be able to land his body shots and the left hook often.

It would probably look like Mayweather vs Mosley but worse.

mosley lost clearly to Cotto. Clottey vs Cotto could have gone either way. Had Mosley not fought Margarito we would all be calling him shot.

A candle flickers violently before dying.

That was possibly Mosley's last hurrah.

Floyd would likely win a UD, but Clottey would be a lot more competitive than Mosley, IMO. Clottey didn't throw a lot punches because Pacquiao hits very hard and quick from different angles and he throws expansive combinations. Against Floyd, Clottey wouldn't be intimidated by the punching power or 1-3 combinations Floyd sometimes throws. Floyd would find some opening to the body as Cotto Judah, and Pacquiao did, but I think Clottey's style could allow him to land his share of precision punches as well.

It would probably be less than thrilling fight, because both guys are natural counter punchers, who wait on their opponent.
