In order to limit the power of legendary superstar Chamberlain in a game, NBA tried to raise the basket to 3.6 meters. As a result, after the game, the opponent complained that the basket was too high and the ball could not be thrown in. Chamberlain could score easily! Therefore, for most players, lifting the basket is not good for them. It is reasonable for NBA to stipulate that the height of the basket is 3.05 meters, because the average height of players is 2 meters. At this height (3.05 meters), players can make some beautiful dunks, which greatly increases the appreciation of basketball games.
