in the 90s, the distance of the 3-point line changed for a couple years?
That’s right. From the beginning of the 1994-95 season through the end of the 1996-97 season, the
3-point line went from 23 feet, 9 inches (22 feet at the corners) to a uniform 22 feet (6.7 m) around the basket.
The change was made as a result of below average scoring games in the seasons leading up to the rule change. Though the average number of 3-point attempts per game increased by over 50 percent, the line was moved back to the original distance after the 1996-97 season because the change had actually
lowered the
average score of games. In the three seasons leading up to the new rule, teams averaged 105.6 points per game. In the three seasons with the shorter 3-point line, that average fell to 100.8.
