The width of the free throw lane (also known as the "key"), increased from 6 to 12 feet (1.8 to 3.7 m).[1]
When teams lined up along the key for a free throw, it became mandatory that the two spaces adjacent to the end line be occupied by opponents of the player shooting the free throw. Previously, one player from each team occupied the spaces adjacent to the end line, with a player from the home team occupying a space marked "H" and a player from the visiting team occupying a space marked "V."[1]
This was the first season in which NCAA basketball was split into two levels of play – the University Division for 156 schools competing at the highest level of play and the College Division for 285 teams playing at lower levels with limited or no scholarships. It also was the first season in which the NCAA held more than one championship tournament — a 24-team tournament for the University Division and a 32-team tournament for the College Division. In 1973, the University Division would be replaced by Division I and the College Division by Division II and Division III.[2][3]
The California Basketball Association was renamed the West Coast Athletic Conference. It would be renamed the West Coast Conference in 1989.
Although it played in the NCAA College Division as a non-major team during the season, Idaho State (25–4)[18] played as an independent and finished the season ranked No. 16 in the final AP Poll.[19]
