For this Since the World's been turning episode we explore another boxing great.  The only man to ever retire as the undefeated heavyweight champion of the world Rocky Marciano. He was one of the real-life boxers that inspired Slyvester Stallone's Rocky’s movies. We’re joined again by Lou Eisen, boxing expert and author of the soon to be released book, Boxing Greatests Controversies: Blunders, Bloodfeuds and Bad Decisions. Marciano’s is a story of triumph against the odds, and true grit. Its the story of how a man who came from nothing was able to win it all.
