The case for Alexander Popov
The 'Russian Rocket', the greatest pure sprint freestyler of the 1990s and a technician of legendary smoothness. Popov won the 50m and 100m freestyle at back-to-back Olympics, Barcelona 1992 and Atlanta 1996, four individual golds and nine Olympic medals in total, along with around six world-championship titles across a long career. Remarkably, he was stabbed in a Moscow street incident in 1996 yet returned to competition and set a 50m freestyle world record of 21.64 in 2000. Coached by Gennadi Touretski, Popov swam with a famously long, relaxed stroke that let him dominate the sprints for a decade, and he remained competitive into his early thirties, an unusual feat for a sprinter, winning world titles in 2003.
The case for Katinka Hosszu
The 'Iron Lady', the most prolific racer of her generation and the queen of the individual medley. Hosszu won three gold medals at the Rio 2016 Olympics, in the 200m IM, 400m IM and 100m backstroke, and set world records in the 200m IM (2:06.12) and 400m IM (4:26.36) that showcased her all-round mastery. She amassed around nine world-championship titles and built an unprecedented career on the World Cup circuit, racing dozens of events per season for prize money and points, hence her nickname. Where most stars pick a lane, Hosszu contested every stroke and distance, and her medley dominance across the 2010s, combining butterfly, backstroke, breaststroke and freestyle at the highest level, made her one of the most versatile swimmers ever.
