He isnt he just has some techniqual issues like the fact that he will throw a combo and pull straight back and be open for a straight right Vargas,Forrest,Cotto exposed that. Also he doesnt have a hard jab he either just flicks it out there or trys to use it as a measuring stick and agianst higher level boxers that doesnt work. But he isnt one dimensonal by any means and he can box. When he fought Oscar he was able to take away his big lefthook by turning southpaw frequently and like in the Vargas rematches he made some adjustments like getting on the balls of his toes and moving away from Vargas straight right and that took away Vargas only chance to win.
