Plenty of fighters get caught with decent shots and just soak it up , Amir hasn't got that in him and fight by fight its getting worse.
I said already punch resistance wise he's shot.
Look back at some of the beatings he's taken ;-)
Khan has got a massive heart and no matter what state he's in he always gets up and wants to fight on.
Always been his downfall but he is pure entertainment.
His only chance against Brook is early on .
