I know where you are going with this and no jr doesn't press like margo and martinez will not fall easily to that style today.
Margarito does, However Chavez will come forward more in this fight southpaws tend to have a hard time fighting going backwards if the orthodox fighter keeps that left foot on the out side.... The difference here is Margarito does pressure like no other but he is slower and much wider with his shots and does not have as tight of a defense as Junior and thats going to make a big difference saturday. People are going to know the first time Chavez connects clean that Martinez is in trouble they will know it right from the outset
