when did the shot clock start in the nba
Shot clock The shot clock first came to use in 1954 in Syracuse, New York, where Syracuse Nationals (now the Philadelphia 76ers) owner Danny Biasone and general manager Leo Ferris experimented using a 24-second version during a scrimmage game.[6] According to Biasone, "I looked at the box scores from the games I enjoyed, games where they didn't screw around and stall. I noticed each team took about 60 shots. That meant 120 shots per game. So I took 2,880 seconds (48 minutes) and divided that by 120 shots. The result was 24 seconds per shot."[3][7] Biasone and Ferris then convinced the NBA to adopt it for the 1954–55 season, a season in which the Nationals won the NBA Championship.
Shot clock Since the 2015â€“16 season, all American college basketball uses a 30-second shot clock, while Canadian university basketball uses a 24-second clock. The American women's game has used a 30-second clock since the 1970s, but the men's game did not adopt a shot clock until 1985. The men's limit was originally 45 seconds, and was shortened to 35 seconds in 1993 before going to 30 seconds in 2015. The National Federation of State High School Associations (NFHS), which sets rules for high school basketball in the U.S., does not mandate the use of a shot clock, instead leaving the choice to use a clock and its duration up to each individual state association. Proposals to adopt a national shot clock for high school basketball have been voted down by the NFHS as recently as 2011.[22] Currently, eight U.S. states require the use of a shot clock of 30/35 seconds in high school competition: California, Maryland, Massachusetts, New York, North Dakota, Rhode Island, South Dakota, and Washington.[22]
