Pacquiao has portrayed Juan Manuel Marquez's knockout blow as a lucky punch, but who's to say how destructive that KO defeat could have been to Manny's psyche? There is a clamor in the Philippines for him to retire, and even trainer Freddie Roach has said he'll recommend retirement for Pacquiao if he should lose Saturday. Meanwhile, Rios, although fully aware that this is the biggest fight of his life, is facing the challenge with confidence and a smile.
