THere is way more on the table for this fight than the fight between Pep and Saddler... MAyweather is also alot faster in comparison to Hatton, and like you mentioned a better puncher. ALso IMO Saddler had way better stamina than Pep, and I think Mayweather has a slight edge in endurance next to Hatton. Last but not least if Floyd finds his jab again its stiff and fast, and even kept Corrales back enough for Mayweather to elude him, and he could use it even better against a guy like Hatton. Last but not least Mayweather has much better defense than Pep, and is a superior inside fighter.
