when was the shot clock implemented in college basketball
Shot clock In the 1969–70 season, women's collegiate basketball (at the time sanctioned by the Commission on Intercollegiate Athletics for Women) used a 30-second shot clock on an experimental basis, officially adopting it for the 1970–71 season.[15] Unlike the women's side, there was initial resistance to the implementation of a shot clock for men's NCAA basketball, due to fears that smaller colleges would be unable to compete with powerhouses in a running game. However, after extreme results like an 11–6 Tennessee win over Temple in 1973, support for a men's shot clock began to build.[16] The NCAA introduced a 45-second shot clock for the men's game in the 1985–86 season, reducing it to 35 seconds in the 1993–94 season[17] and 30 seconds in the 2015–16 season.[18] The NAIA also reduced the shot clock to 30 seconds for men's basketball starting in 2015–16.[19]
Three-point field goal Used only in conference play for several years, it was adopted by the NCAA in April 1986 for the 1986–87 season at 19 ft 9 in (6.02 m)[24][25][26][27] and was first used in the NCAA Tournament in March 1987.[28] The NCAA adopted the three-pointer in women's basketball on an experimental basis for that season at the same distance, and made its use mandatory beginning in 1987–88.[29] In 2007, the NCAA lengthened the men's distance by a foot to 20 ft 9 in (6.32 m), effective with the 2008–09 season,[30] and the women's line was moved to match the men's in 2011–12.[29] American high schools, along with elementary and middle schools, adopted a 19 ft 9 in (6.02 m) line nationally in 1987, a year after the NCAA.[31] The NCAA used the FIBA three-point line (see below) in the National Invitation Tournament (NIT) in 2018.[32]
