Pacquiao vs. Hatton would be a nice fight, but...?

I don't think you can compare the fighters in that way. Firstly just a minor point but Mayweather's victory over Hatton was TKO and not KO. Secondly I think Hatton is better now than he was last year. Also Hatton will likely have 90000 Brits cheering him on and that has to give him a huge lift. I don't think Manny would beat Mayweather and their respective fights with De la Hoya were against a very different Oscar.
