If Clottey beat Pacquiao, would it be the biggest upset in boxing history??

The thread says Clottey KNOCKING OUT Manny.

Thread I saw said "If Clottey beat Pacquiao, would it be the biggest upset in boxing history??" Doesn't mention "knocking out".

i dont think it'd quite be in Buster Douglas territory, but I'd still be shocked if Clottey managed an upset. I just don't see it happening, unless Pacquiao does something to defeat himself...

Would it fuk. If you'd have said Pacquiao vs Clottey 2 or 3 years ago, Pacquaio winning would've been seen as a bigger upset.

It would be a big upset if Pac loses. But is Clottey a more worthy opponent than Douglas was supposed to be? I would have to say yes.
So it wouldnt be as big an upset as the Tyson and Buster one, only because CLottey is more regarded i would say.
He did beat Cotto some people say in his last fight and you are as good as your last fight they say
