Many analysis and articles have already been written by some experts and so-called experts about this subject in the past week. My take on this matter is simple...Juan Manuel Marquez has a weak chin. He was decked by another Filipino Jimrex Jaca and recently by Marco Antonio Barrera. If Pacquiao's so-called weakness is his boxing skills then Marquez weakness is his chin. If you ask me Pacman's weakness can be remedied through training while Marquez isn't. I don't know how long will Marquez avoid Pacquiao but in a boxing match the Mexican will be hit...no amount of boxing skills could save a weak chin. Hopefully Marquez will fall right away!
