I've seen him make mention of this on more than 1 occasion. But put it into its proper context, he was mentioning the weight drained versions of guys Pacman fought at WW- specifically he mentioned Cotto and DLH- and how he's not like either of them were when they fought Manny (in the sense they were both weight drained.) Essentially he was saying he'll be taking on an actual WW and not one of these weight-drained welter's.
This is bs. He's saying that pac wears lifts in his shoes. He actually thinks pac is small for WW and he really is a big WW.
