if pacquiao beats margarito and decides to up to middleweight and fight either martinez or williams, that would be suicide because for one, williams, aside from his physical advantages he would have against pacquiao, has a very solid chin and i seriously doubt pacquiao has that kind of power to topple a 6'2 fighter. same with martinez, who i think he's right at his prime at the ripe old age of 35. this would be a mismatch and i don't think roach would want any of these fights.
