The 1972 Olympic men's basketball was one of the most controversial events in Olympics history. This was the first ever recorded loss of Team USA from the beginning of the game in 1936. The United States team won the previous seven gold medals and was primed for yet another heist. At that time, The Cold War was at the culmination point and also fueled the rivalry.
According to official documents, the final score was 51-50 and Soviets had their first Gold in Basketball. While the USA Basketball Team refused to accept the silver medal owing to the irregularities in final seconds of the game when the score was level.
Till now, it remains to be the greatest controversy of Basketball. Team USA hasn't accepted the silver medal officially.
