The case for Mark Spitz
For 36 years the standard by which all Olympic swimmers were judged. At the Munich 1972 Games, Spitz won seven gold medals in seven events, every single one in world-record time, a perfect performance not surpassed until Phelps in 2008. Across two Olympics he collected nine golds and 11 medals in total, and over his career he set 33 world records in freestyle and butterfly. He retired at just 22, at his peak, before the World Championships even existed (the first were held in 1973), which is why his title tally sits outside that column. His combination of sprint speed and butterfly power, and the sheer perfection of Munich, keeps him among the immortals despite his short career.
The case for Ian Thorpe
The 'Thorpedo', the finest middle-distance freestyler of his generation and a national hero in Australia. Thorpe won five Olympic gold medals and 11 world-championship titles, dominating the 200m and 400m freestyle and repeatedly lowering the 400m world record toward the 3:40 barrier. At his home Sydney 2000 Games, aged 17, he won the 400m freestyle in world-record time and anchored a stunning relay victory over the United States. At the 2001 Fukuoka World Championships he won six gold medals. Renowned for his size-17 feet, immense reach and metronomic stroke, Thorpe combined precocious success with genuine longevity across two Olympic cycles, and remains, statistically and stylistically, one of the most complete freestylers the sport has produced.
