I think once Hatton goes back to his confort zone at 140 he will be hard to beat by most at that weight. His style is most effective against smaller fighters that cannot coup with his preassue and strength. He'll be able to manhandle his opponents at 140.
Still Hatton's style of fighting and living often leads to short careers and I would not be supprised if he lossed to some of the current champions at 140.
