The funny thing is that Oscar used as intelligent of pressure as I've seen used. He was patient, and he kept his hands up so Mayweather could pot shot him effectively with his hardest punches, and Oscar was holding his punches or using his jab to get Mayweather on the rope and then he threw awkward combinations that were always thrown with a different tempo. Hatton tends to come in at the same speed and he will be easy to read as the fight goes on, also there is a the little space where he can be countered when he opens up, and Mayweather is fast enough to find it because Collazo also found it, and Collazo doesn't fight at the elite speedsters'(Judah, Mayweather, Mosley) pace though he has the potential for it.
