Pacquiao’s performance was so good that no one laughed when promoter Bob Arum said he believes Pacquiao is the best fighter he ever saw. And yes, Arum included Muhammad Ali, Sugar Ray Leonard and Marvelous Marvin Hagler in that group.
Bob Arum has seen more fights than most of us put together....He knows his shit....for him to state that means a little more than anonymous people on the internets bickering over who's the best.
