A 5'10" Heavyweight Went 49-0 And Knocked Out Everyone

A 5'10" heavyweight went 49-0 and knocked out every single title challenger. After World War II, Rocky Marciano redefined the division starting in 1952. Overcoming a major size disadvantage with relentless pressure and endless stamina, Marciano defended his belt six times—winning every defense by knockout against hall-of-famers like Ezzard Charles and Archie Moore. After retiring undefeated in 1956, Floyd Patterson and Ingemar Johansson traded the title in a massive TV trilogy, setting the stage for the arrival of the most feared force in boxing: Sonny Liston. Could Marciano's raw pressure style beat modern 6'6" heavyweights, or was he simply too small for today's ring? Drop your take below!
