its virtually the same fighter except rocky a little,taller,heavier,stronger,and even a little tougher kinda like duran vs dempsey or floyd jr vs patterson the bigger of all 3 win it
I think he means p4p so the bigger one doesn't apply man. But anyhow i pick Rocky to win cause Marciano was a bigger puncher whereas although Fullmer was physically very strong he was not the power punching menace that Rocky was.
P4P matches are difficult to do how much would they weight? How tall? What reach? A guy like Hearns had great reach on his opponents but make it a p4p match against Ali and who has the greater reach how will this effect the fight how good does his chin hold up at heavy if the p4p match up is their how quick would Tommy hands be at the weight etc. There are no many tangibles to make an accurate pick.
