How hard is it to pick an opponent for someone as big as manny pacquiao and not get unfairly criticized?

It's extremely hard because Pacman is just so unbeatable at this point of his career. The guy has it all: talent, athletic ability and physical prowess. Most of all, he's at his absolute peak and appears to be getting even better. He'll get criticized whomsoever he fights, except Floyd Mayweather Jr.
