Mayweather lets his hnds go when the fighter is/at his size.

[DrewWoodside]

Judah
Mitchell
Gatti
Hatton
Castillo
Ndou
JMM

Against fighters way bigger then him he doesnt let his hands go:

Oscar
Baldimir





So add Pac to the list...Floyd is letting his hands go..and everytime he does its fightening.

Ask Hatton when Floyd start letting his hands go.

Ask Hatton when Pacquiao starts letting his hands go. If he says nothing, it's because he has zero memory of the experience.
