Wow its one extreme to the other first of all, No Mayweather not knock Hatton out if its toe to toe, look at the Castillo fight, Mayweather couldn't get off when Castillo held him, and thats all Hatton has to go on the inside, and yes Mayweather is startled by Hatton, but that means nothing come fight night. Hatton is a real opponent and nothing is out of the realm of possibilities except perhaps Hatton scoring a knock out.
