If you really think about JMM's biggest accomplishment is giving Pacquiao problems. He struggled with Juan Diaz at 135, he lost to little known Chris John, lost to Freddie Norwood, even struggled with a shot Joel Casamayor.He didn't win 1 round against Mayweather. People had their nose up his ass even BEFORE the Pacquiao knockout, and the knockout doesn't take away the fact that he lost to Pacquiao twice before. So lets say this topic was made PRE-PACQUIAO KNOCKOUT, is troubling Pacquiao his biggest claim to fame?
