Even if Pac loses I think Floyd will make the Pac fight. Its still the fight people want to see. They'll say Cotto was too big for Manny.
you just answered your own question..
both floyd and manny blown up lightweights
they are both blown up lightweights ( so neither will have the natural welterweight advantage) and the fight will be for $30+ million. Turning down a $30+ million fight with a guy ( in PAC) that is your size is not good business....PBF understands good business and a fight with PAC is good business.
