agree ko nimo, ngots!
a 10-5 record against top ranked opponents is much more impressive than a 15-0 record against mediocre opposition.
pbf's 40-0 record is mostly against opponents, who we already know, do not possess the skill-set to beat his style.
mayweather is a great boxer with impressive skills who can sell tickets and ppv's. but that is all there is to it. pbf is a product of the media hype machine. pbf can't make it through an hour without talking about how great he is. if you constantly hear the same crap all over from the media, pbf is p4p #1, pbf is unbeatable, pbf this and pbf that. sooner or later your bound to believe in the crap thats being fed to you.
until pbf fights somebody who will actually give him a fight, this debate will forever be a monkey on his back.
