I agree that Chavez is good fighter, He comes to fight but I dont think he is very skilled boxer thou. The word sweet science does not fit on Jr very well... Jr is exciting and his style is fan friendly if you give him suitable opponent. Tough fight for everyone not named Martinez. So can he learn from his mistakes? He has had plenty of time already and **** loads of fights...He already has heart of a fighter but does he have the talent or hunger to learn.. Time will tell.:think
