possession of the ball was introduced in 1933, where teams were required to advance the ball over the center line within ten seconds of gaining possession. This rule remained until 2000, when FIBA reduced the requirement to eight seconds, the NBA following suit in 2001. The NCAA retains the 10-second rule for men's play, and adopted this rule for women's play starting with the 2013–14 season. U.S. high schools, whose rules are drafted by NFHS, also use the 10-second rule for both sexes. In 1936 the three-second rule was introduced. This rule prohibits offensive players from remaining near their opponents' basket for longer than three seconds (the precise restricted area is also known as the lane or the key). A game central to this rule's introduction was that between the University of Kentucky and New York University. Kentucky coach Adolph Rupp did not take one of his referees with him, despite being warned of discrepancies in officiating between the Midwest and East by Notre Dame coach George Keogan, and the game became especially rough. Because of this game and others, Kentucky All-American center Leroy Edwards is generally recognized as the player responsible for the three-second rule. While the rule was originally adopted to reduce roughness in the area between big men, it is now considered to prevent tall offensive players from gaining an advantage by waiting close to the basket. When the NBA started to allow zone defense in 2001, a three-second rule for defensive players was also introduced. The shot clock was first introduced by the NBA in 1954, to increase the speed of play. Teams were then required to attempt a shot within 24 seconds of gaining possession, and the shot clock would be reset when the ball touched the basket's rim or the backboard, or the opponents gained possession. FIBA adopted a 30-second shot clock two years later, resetting the clock when a shot was attempted. Women's basketball adopted a 30-second clock in 1971. The NCAA adopted a 45-second shot clock for men while continuing with the 30-second clock for women in 1985. The men's shot clock was then reduced to 35 seconds in 1993, and further reduced to 30 seconds in 2015. FIBA reduced the shot clock to 24 seconds in 2000, and changed the clock's resetting to when the ball touched the rim of the basket. Originally, a missed shot where the shot clock expired
