Pacquiao has this reputation as someone who is not really a defensive wizard. We say that he doesn't concentrate much in his defense because he focuses more on his offense. Hence, we can see those threads saying that he got hit a lot against Cotto. Mosley on the other hand is someone we can say is a great boxer who also has a good defense. He takes care of his defense more than Pacquiao. Or is it? Maybe facts can give us some idea of their defensive skills. They have a common opponent (Cotto) and we can use their fights against Cotto to gauge their defensive skill. Here are Cotto's stats against Mosley and Pacquiao: Total punches (landed/thrown/%): (against Mosley) 248/675/37% | (against Pacquiao) 172/597/29% Jabs (landed/thrown/%): (against Mosley) 98/288/34% | (against Pacquiao) 79/297/27% Power punches (landed/thrown/%): (against Mosley) 150/387/39% | (against Pacquiao) 93/300/31% Basing on those data, we can see that Cotto not only threw fewer shots against Pacquiao, but he also landed fewer of his shots against Pacquiao. Does Pacquiao really lack defense or are we just conditioned into thinking that he lacks defense?
