User:US Referee/NCAA men's basketball rules trials

The Big Eight Conference first considered adopting a 30-second shot clock prior to the 1972–73 season. There was some indication also that other lengths may have be considered. Conference stakeholders in May 1972 unanimously approved a 30-second shot clock to be used in the conference pre-season tournament, regular season conference games, and home non-conference games subject to the visiting school's consent. In spite of the unanimous vote, some coaches expressed regret for voting for the rule change. Nevertheless, reception was generally positive and stakeholders in May 1973 again voted unanimously to approve the rule for a second season. . The Southwest Conference also voted to implement the 30-second clock for the 1973–74 season.

However, enthusiasm waned and in 1974, Big Eight rule was modified to start the clock when the ball crossed the division line, while the Southwest Conference narrowly chose not to renew the rule.
