Editing Shot clock (section)

===Collegiate rules===
American collegiate basketball uses a 30-second shot clock, while Canadian university basketball uses a 24-second clock.

In men's collegiate basketball, there was initial resistance to the implementation of a shot clock for men's [[National Collegiate Athletic Association|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 Volunteers basketball|Tennessee]] win over [[Temple Owls men's basketball|Temple]] in 1973, support for a men's shot clock began to build.<ref name="tntempleshotclock">{{cite web|url=http://www.govolsxtra.com/news/2007/nov/07/night-crawler-temple-set-stage-for-time-clock-in/|title=Temple set stage for shot clock|last=Strange|first=Mike|date=2007-11-07|publisher=[[E.

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 in the 1969–70 season, officially adopting it for the 1970–71 season.<ref>[http://web1.ncaa.org/web_files/stats/w_basketball_RB/2008/2008RB.pdf Official 2008 NCAA Women's Basketball Records Book], p. 245</ref>

The NCAA specifies 20 seconds rather than 30 after stoppages where the ball is already in the frontcourt. In 2019, it added offensive rebounds to this list.<ref>{{cite web|url=https://www.ncaa.com/news/basketball-men/article/2019-11-05/mens-college-basketball-rule-changes-know-about-season|title=The men's college basketball rule changes to know about this season|first=Andy|last=Katz|publisher=NCAA|date=November 5, 2019}}</ref>
