Fair or not, Pacquiao will ALWAYS be remembered for getting KTFO by Marquez
despite all of Manny's accomplishments, the truth is this is what will stick in people's mind forever. Yes every fighter eventually loses, but it's not like Manny was some old shot fighter who accumulated late-career losses like Ali or Roy. He got knocked out cold by a fighter 6 years older than himself.
It's pretty sad, but unfortunately people will always remember Pacquaio as Pacquaio'd
