Roy Jones did it, obviously it fucked him up, but you have to take into consideration how fast he did it, De La Hoya never weighed in at 160, he weighed in at 154 or 155 against Hopkins which is pretty much staying at LMW. He has had 3 years to lose the weight effectively. He had no troubles with stamina or anything else against Forbes at 150, if you are asking do I think Oscar can make 140, no I don't, but I said he would have had trouble making it in his prime just like Cotto did against Paulie. I am saying Oscar was 147 in his prime, and there are ways to get back down to that safely, and he has taken every step properly to insure that he gets there in peak shape. He hasn't been bloating up between fights, and he's a lot more focused on his boxing this last year.
