Alright you got this a bit mixed.
Pacquiao does want to fight Floyd, but heres the issues.
#1- Pacquiao wants to do it for Charity. Pretty stupid the fight could have happened awhile back when Mayweather offered him 40 million, but now he wants to fight for free.
#2- Mayweather does not fight for free. He's a money guy that loves money over legancy. Which is fine cause he's got a solid resume and has nothing else to prove
#3- Bob Arum has to get paid (Pacquaios Boss)
#4-Pacquiao can't do whatever he wants again he's got a boss. Not a free agent
.
As for Mayweather it doesn't really matter. At this point now in his career he's just milking boxing for what it's got left in it.
Yes if he wants another big pay day he can go for Amir Khan
Or if he wants to please the fans he can go for Maidana which would be another big fight.
Personally i'd like to see him fight these guys before he leaves (Excluding Pacquiao) i'd love to see that fight
Serigo Martinez
Timothy Bradley
Lara
Macros Maidana.
Hell you can even throw Keith Thurman in the mix.
