Mayweather proved a class apart. Probably his best fight in years and the KO was nice, from his POV. However, I do think the ref spoiled things a bit, especially early on, Hatton needed to be allowed to fight on the inside, and he wasn't, although Floyd proved he could also mix it on the inside. The point he took away was BS too. Also, Hatton was fighting at the wrong weight, his power wasn't as impressive at this weight and Floyd's power surprised him.
Mayweather clearly the better fighter though.
