The history of the slam dunk: from outlawed move to beloved highlight

The NBA Slam Dunk Contest has become an institution in modern basketball. But for years dunks were outlawed in college and high school games

It seems impossible to believe, but there was a time when basketball largely forbade the dunk. From 1967 to 1976, high school and college players were outlawed from slamming the ball through the rim. Instead, they would have to lay the ball up or simply drop it through the hoop as they soared through the air. Now, as we look forward to this weekend's NBA Slam Dunk Contest, the ban seems silly, especially when considering the eye-popping highlights created by the likes of Michael Jordan, Dominique Wilkins, Shawn Kemp and Vince Carter.

But such was the state of things a half-century ago. In an era when the game was changing rapidly, when players like the 7ft 2in Kareem-Abdul Jabbar were dominating instead of the shorter, more ground-bond hoopers like Bob Cousy, the dunk was seen as taboo among purists," against the very nature of basketball itself. Though that perspective wasn't shared by many of the players.
