Why they rank here
A generational talent and one of the most physically gifted attackers ever to play, Leon became the youngest man to appear at a senior World Championship at just 14 for Cuba. After leaving the Cuban programme he adopted Polish citizenship and joined one of the world's strongest national teams. His trademark is a colossal jump serve, among the hardest ever recorded at well over 130 kilometres per hour, that can dismantle a reception single-handedly, allied to explosive outside attacking. At club level he won consecutive CEV Champions League titles with Russia's Zenit Kazan in 2015, 2016 and 2017, dominating the strongest club competition on earth. International gold with Poland has proved elusive amid fierce competition, but on raw ability, serving power and highlight-reel athleticism, Leon stands among the most dangerous players of the modern era, a fixture in every conversation about the best current outside hitters. As of the 2024-25 season he remained a leading force.
