If Marciano had come back against Ingemar Johansson in '59-'60?

I tend to think along the lines of most....without the drive, hunger and fitness he had in his prime he gets hit with the toonder as he tires and is stopped later, which in my opinion was quite a bit heavier than Archie Moores right hand as formidable as it was

 

A 28 yr old Ingo beats a 37 yr old Rocky, Looking at photos of Rocky in 1960 time frame, he looked way out of shape, and by his own admission enjoyed the pleasures of retirement fully.

Rocky did the right thing, stayed retired and preserved that 49-0 record.
