JJ isn't the hardest P4P puncher either. Even in the very modern era, G-Man, RJJ, Tyson hit harder P4P.

Hardest P4P puncher of all time might be Marciano. I know he was an HW, but the guy weighed 184 without cutting weight.
Well whatever but he still was feather fisted as amateur and your trying to tell me that RJJ hit harder than Jackson p4p ??
