Yeh, I thought Cotto was gonna take this--especially after seeing the way Mayweather handled a very similar Ricky Hatton. I kinda figured smart boxing would overcome resilience again, but obviously Hatton and Margarito are not cut from the same cloth.
Calzaghe's nice too. Such a shame he's spent almost all of his career fighting outside of the US. Now he's old and on the wane. He won't last too long fighting the caliber of boxers we have over here. He DID dismantle Peter Manfredo pretty handily though. I thought he beat Hopkins pretty clearly as well. Would have been nice to see him fight the likes of Roy Jones Jr. in their primes. Ooooooooh.
Pavlik is alright in the middleweight division, but who's his real competition--after beating Taylor? Edison Miranda has shown some promise, but it'll be a while before he's ready for Pavlik. He's got to work on his endurance, he's got to become more disciplined, and he needs to strengthen his defense. He's been training in Puerto Rico for the past couple years, though, so he WILL get better.
Klitchko has no real competition. The heavies are boring these days. The Leaonard/Duran "No Mas" fight is classic, as is Leonard/Hearns. Vazquez/Marquez, and Pacquiao/Barrera were nasty too.
I don't know about a Cotto/Margarito rematch yet. I think we need to see how Cotto bounces back. He'd never lost before, and then to have to take knees twice...

It's the kinda stuff that can destroy a guy.
I hope he has the heart and courage (and the brains) to take a rematch, and then really work on his stamina. I know Paul Williams beat him not too long ago, but then he came back and DESTROYED Kermit Cintron. He's a tough fighter, man...and to train strictly for stamina is gonna be hard for Cotto. I guess we'll see.
