Another thing that isn't fair - qualifying for the all-around or event final and then getting replaced by your coach for someone else who he thinks deserves it more or has a better chance of medalling.
[quote]In the run-up to the 1996 Olympics, the world seemed to be Alexandra Marinescu's oyster. After winning the European junior title twice and helping her team to the gold medal at the 1995 World Championships in Sabae, Japan, she took a silver medal on the balance beam at the 1996 World Championships in San Juan, Puerto Rico. Coming to Atlanta, the blonde Bucharest native was expected to be a front runner for the coveted all-around title. She seemed to have it all- style, difficulty, the perfect body, the perfect age, the perfect gymnast. Only it never happened. Marinescu never even competed in the all-around competition in Atlanta despite having qualified to it. The Romanian team management decided to substitute her with team mate Simona Amanar, who went on to win the bronze medal. The same thing happened at the World Championships, held in the Swiss town of Lausanne a year later - Marinescu qualified to the all-around, only to be replaced by Amanar, who this time took the silver. "I am very grateful to Alexandra, " Amanar told the press in Lausanne, "because she let me compete and win this medal." Lausanne was to be Marinescu's last major competition as a back injury forced her out of the sport later.[/quote]
