froch, ward, sergio, kessler, dirrell, abraham etc ...have done against the beast that was Hagler? who could have given him problems?
I'm a 90's kid, so basically to me, RJJ was superman. I think he UD's Hagler, but he's in much more danger vs Tommy Hearns.
They would all give Hagler various problems to have to cope with but I don't see any of them beating the marvelous one.
