The NBA Draft Combine is a multi-day event, usually conducted around a month before the NBA Draft.
The Draft prospects - mostly college basketball stars - are measured, taken for medical tests, interviewed and asked to perform multiple drills including various athletic tests and shooting drills in front of an audience of coaches, general managers, and scouts from multiple NBA teams.
One of the most interesting physical tests that the prospects have to undergo and receives the most eyeballs is the vertical leap.
