I think what would really shut up the critics is that if Khan takes on a guy like a Maidana or a Torres and wins. There are still a lot of questions that Khan still has to answered, but this fight imo is a step in the right direction.

Hell just take a look at a guy like Ricky Hatton who fought mainly bums for his first 33 or 34 fights and then catches Kostya when he's on the downside and everyone is singing his praises like he's the 2nd coming of Aaron Pryor and calling him an all time great.
