Basketball used jump balls to determine possession until 1937 when the team that did not score received the ball. In 1981, the alternating possession rule was enacted. Other NCAA basketball rules include designated free throw shooters, no coaching during games in 1910-1911, and no climbing walls to reach the basket.
Basketball teams have not always alternated possession of the ball. A jump ball, in which an official tosses the ball in the air between two teams attempting to gain control of it, was used by the National Collegiate Athletic Association (NCAA) from 1930 to 1937 both after each field goal and when a ball has been thrown out of bounds. After 1937, once the field goal was made, the ball was given to the other team and jump balls were only used to determine possession of offside balls. In 1981, the alternating possession rule was enacted. An opening jump ball is used to decide which team receives the ball initially and then alternates during offside situations.

One player was designated per team to shoot all free throws, or unblocked chances to make a field goal due to violations by the opposing team, until 1923.
From 1910 to 1911, it was against NCAA basketball rules for coaches to provide guidance during the game itself.
Once upon a time, basketball players could climb the wall to get closer to the basket. However, this was eliminated in 1921, when the basket was moved 2 feet (0.62 m) from the wall and ruled out of bounds.
