Floyd Mayweather is a bitch. Stick and move. He has NO KO power, and just tries to score and get out.
He is lightning fast, but Hatton has quick and powerful hands, from both sides. I do not know is Hatton is patient enough to take the fight to Mayweather, but I am willing to bet there is a 24 foot ring as Mayweather will get this to give him room to run.
I am laying a small bet on under 12 rounds and Hatton +200. Who knows, Hatton could catch him with that left.
