I took a look at his best knockouts the other day and now I will look at his toughest opponents. To tell the truth, to find 10 was kinda tough. He really hasn't had a really close challenge since 2008.
Even early in his career when he was a one-handed destroyer, he didn't have that much trouble with opponents. I also had to consider what "tough" meant. Does that mean that he had trouble with them or was one particular fighter just one tough dude?
I split the difference and went with tough guys who had decent records. If Pacquiao struggled against them, then they got moved up the list. You do have to remember that Pac-Man having a tough time with someone nowadays means he loses a round or two.
