Funny that since this thread was made there had been none noteworthy until Pacquiao got wrecked last month. That really will be a historical KO, Manny is the only ATG other than Roy Jones to suffer a bad knockout in many years. I guess that speaks more to their having only been a few really "great" fighters active, but still. Manny isn't chinny and he'd never seen the canvas in 36 rounds against Marquez, it was a monster punch.
