marquez, guzman, and valero.

pacquiao in a league of his own? that's the fan in you talking, man. granite chin? dude, c'mon. he hasn't met any real heavy hitter. sure, he would go in as a favorite against any opposition at his weight class these days. i won't bet against the man. but he is not as invincible as you rabid flip fans think. i say, marquez, guzman and valero all stand a fair chance.
