when did the nba 3 second rule start
Three seconds rule The three-second rule was introduced in 1936 and was expressed as such: no offensive player with the ball could remain in the Key with or without the ball, for more than three seconds.
Three-point field goal Three years later in June 1979, the NBA adopted the three-point line for a one-year trial for the 1979–80 season,[9][10][11] despite the view of many that it was a gimmick.[12] Chris Ford of the Boston Celtics is widely credited with making the first three-point shot in NBA history on October 12, 1979; the season opener at Boston Garden was more noted for the debut of Larry Bird (and two new head coaches).[13][14] Rick Barry of the Houston Rockets, in his final season, also made one in the same game, and Kevin Grevey of the Washington Bullets made one that Friday night as well.[14][15]
