NBA Girl Making A Slam Dunk

Dunking was banned in the NCAA from 1967 to 1976. Many have attributed this to the dominance of the then-college phenomenon Lew Alcindor (now called Kareem Abdul-Jabbar) upon his entry into the NCAA. Subsequently, the no-dunking rule is sometimes referred to as the "Lew Alcindor rule."
The phrase "slam dunk" has since entered popular usage, meaning a "sure thing" – an action with a guaranteed outcome.
