gassed?, only time ive known hatton to gas is when he moved up weight and never did it the right way (against collazo).
every other time its been constant pressure for 12 rounds (if it went that far) look at the kostya tszyu fight, that guy is a living legend in boxing but he wouldn't get out of his seat for the last round.
i know he's moving up weight again for mayweather but i think he's prepaired himself properly this time.
ps:- didn't mayweather look shook-up at the weigh in?
i don't know if thats him being smart and not trying to over-excite himself (adrenline) before the fight, but he really looked shaken in his face expression.
against oscar de la hoya mayweather was dancing around in his face at the weigh-in so i don't know.
