Floyd at 130.

[bradlee180]

Meh he quit twice so he had quit in him.

De La Hoya quit.
Roger Mayweather quit.
Julio Cesar Chavez quit.
Mike Tyson quit.
Vitali Klitschko quit.
Kostya Tszyu quit.
Erik Morales quit.
Alexis Arguello quit.
Sonny Liston quit.
Devon Alexander quit.
Shane Mosley was begging for someone to stop the Pacquiao fight. "I can't move."

Genaro Hernandez quit against De La Hoya a couple years before Floyd fought Hernandez.
Victor Ortiz quit a couple years before Floyd fought him.
Miquel Cotto conceded on his stool a few years before Floyd fought him.



EDIT:

I do not believe Floyd, he was in training at it was 157lb at one point so find this hard to believe.

It sure didn't look like 17 pounds difference to me when they were fighting.
