Re: Rocky Marciano or Jack Johnson who was the greater fighter?
Johnson is staggeringly overrated. He was troubled by many, many supposedly lesser and definitely smaller fighters. Only his legions of myth-hungry, hero worshipping fans- a veritable publicity machine- keep the idea alive that he was a truly great fighter.
Marciano, to a lesser but equally aggravating extent, has a multitude of over-inflators in regards to his ring value.
Head to head, Marciano would blow Johnson out of the ring. Legacy-wise (boxing legacy not social legacy) they are much closer but I give Marciano the nod.
