martinez is a horrible style matchup for pacquiao. he presents an even larger size threat than margarito and to top it off he's a very mobile, fast punching natural junior middleweight with magnificent stamina and resiliency that mirror's manny. he isn't gonna be waltzing straight into manny's fire power the way margarito did; those type of fighters make the little guy look godly despite any size advantage. keep in mind that the one and only clean body shot margarito landed in the fight (during the 6th round i believe) nearly crumbled manny and he had to be hospitalized for that...just one clean punch from a dude as slow as molasses.
if this fight happens he's gonna force martinez to kill himself at the scales at yet another stupid fuckin' catchweight.
