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.
The case for Ryan Lochte
Phelps's great rival and, on his day, the only man who could beat him. Lochte won six Olympic gold medals and 12 Olympic medals overall across four Games, specialising in the individual medley and backstroke, and set world records in the 200m IM (1:54.00) and 200m backstroke. He was one of the most decorated swimmers in World Championship history, with 27 medals across long-course and short-course events, a testament to his range and durability. Fearsomely versatile, he pushed Phelps in the 200m and 400m IM and the 200m backstroke throughout their careers, often forcing world-record swims. A dominant medley racer whose reputation off the pool was later dented, Lochte's competitive record places him firmly among the greats.
