One is a hall of famer (Hearns), the other a pretty limited and stiff boxer (Jackson). BUT they are a lot bigger and harder punchers than the ones around Floyds era. We only have one massive puncher Floyd ever went up against, Mosley, and he landed 1 bomb and never did a damn thing after that in the fight. He's quite a bit smaller than those guys though. Any ideas on if Mayweather could handle big boxers who are also power punchers? He faced on guy who is bigger than both but not a great puncher or boxer.
