I am really surprised with Juan Manuel Marquez. I dont understand why he rejected Amir Khan and it would be Amir defending his belt which would have made Marquez the only Mexican to win 4 titles in 4 divisions. Not to mention, he would make more than twice the money he would make with Amir Khan than Juan Diaz. Juan Diaz may be washed up after the brutal knock out that Marquez gave him and Diaz also lost recently to light punching Paulie Malignaggi. I dont understand why Marquez did this? Can someone explain why Juan Diaz and not Amir Khan?
