Prescott has been exposed as a limited fighter , Maidana is pretty limited , however he can punch hard , so if Khan man's up ,fights and beats him UD , then we know he has the skills to avoid power and win. ( as he cant improve his weak chin )
By not fighting him is fuelling the criticts , that Khan and his camp know the first world class puncher who hits Khan on the chin , showers the first three rows of fans with broken glass.
