The answer is NO Rocco, you are not moving in lol

As for Marciano... He doesn't have the frame to compete with a modern HW no matter how much steroids you give him. After a point he'd be a muscle bound midget, he'd be too slow and stiff to hit anything and his power would drop of considerably the heavier he got with respect to his new class of opponents.

Rocky's skills, heart and will were no better than Brewster had imo.
