I agree, Pacman doesn't have to prove himself again because he already carved his name in the boxing industry and have achieved a feat that will be hard for any boxer to attain.
That's why if he wants to fight again, there will be a lot of boxers that would be happy to fight against him. It is because of the fame that's attached to him and for those boxers, it's an honor to have a match against him.
What I can see with those new boxers that would still like to fight against him, it's like quick fame and career boost whether they'll be beaten or win against Pacman. That's what Ryan Garcia tried to do but Pacman didn't bite his words.
Yes, it will be an honor to any boxer out there who gets a chance to fight Pacquiao even if it's just an exhibition fight and aside from the fame, money will always follow Manny Pacquiao that's why there has been reports and rumors that boxers are trying to get him into fights especially now that he is older enough and at that time, he didn't made a statement to retire yet.
Ryan Garcia did that? Didn't know that at all, surely the kid has something to offer but Manny wanted good and safe fights for now that's why Manny didn't bother at all.
