True, but when does he get involved in a real "fight"? I think Hatton may ultimately have more stamina, but Mayweather is a master at minimising energy wastage. This fight will be about who can dictate the pace. Whoever can impose their style will last the pace better, but stamina is not an issue for either man.
Hatton has very good stamina, but Mayweather is the fittest boxer in the world. Has he ever even looked like gassing out?
Anyone who says they've never seen Hatton tired must NEVER watch Ricky Hatton. In 2 of his last 3 fights he looked QUITE tired by the end, against both Urango and Collazo. Against Castillo he looked like he could fight forever, but he KOd Castillo early so that means NOTHING.
