with a victory over mayweather jr. there's no doubt pacquiao will be one of the top two or three fighters in this decade but to say he would be the greatest fighter of all-time is really wishful thinking. for one, like any other great fighter, there are holes in pacquiao's resume. sure he's come up impressively and beaten heavier fighters but were those fighters on the decline or overrated at best? the facts are these, the fighters of yesteryear didn't have the luxury to pick and choose easier opponents because there was only one world title per division along with only 8 weight divisions. sure pacquiao holds the record for 7 world titles but look how many are there in each division? not to mention there are more than twice the divisions (17) currently as the original eight. a victory over mayweather would put pacquiao no higher than maybe 18-20ish. if he wants to further his p4p standing he should fight a few more years and have at least 80 fights like the oldies used to do it.
