How fast is Malinaggi?

Everyone keeps saying Malinaggi has fast hands - how fast are they compared to the likes of Mayweather, or the old Mosley? He doesn't really have power going for him, so speed and technique are his only two advantages. His chin is untested - so we can't comment on that. Mayweather, with brittle hands and little power, has gone far enough for most people to call him the p4p king - and i know Malinaggi has less power than mayweather, but is he as fast? And if he is, and builds as much skill, is it possible that he'll be succesful in the game?
