The case for Caeleb Dressel
The sprint-butterfly heir to Phelps and one of the most explosive swimmers ever. Dressel won eight Olympic gold medals through Paris 2024, including a five-gold haul at Tokyo 2020 across the 50m and 100m freestyle, 100m butterfly and both American relays. He holds the 100m butterfly world record (49.45) and has been part of numerous world-record relays. At the 2017 Budapest World Championships he matched a single-meet record with seven gold medals, and across his career he has accumulated around 15 world-championship titles. Renowned for enormous power, a ferocious start and underwater speed, Dressel is the defining sprinter of the textile-suit era, though a mental-health break and a tougher Paris meet showed the toll of racing at the extreme.
The case for Kosuke Kitajima
The greatest breaststroker of his era and a Japanese national icon. Kitajima achieved a feat no other man has managed, winning both the 100m and 200m breaststroke at two consecutive Olympics, Athens 2004 and Beijing 2008, a breaststroke double-double, for four individual golds and seven Olympic medals overall. He set multiple world records in the 100m and 200m breaststroke and won world-championship titles across the 2000s. Famous for his aggressive, powerful pull-out and racing intensity, Kitajima's Athens victory came amid a controversy over an illegal underwater dolphin kick that helped prompt the 2005 rule change legalising a single kick in the pull-down. He defined breaststroke for a decade before Adam Peaty raised the event to another level.
