In show business lexicon, a "Green Room" is the space backstage used to house performers. It is a waiting room, a lounge to gather in until they are required on stage or to unwind once their part of the performance is finished. It is fitting, then, that the area used to house the top prospects in the NBA draft has been dubbed the Green Room.
It is in the Green Room that these players and their families bide their time until they are beckoned onstage to shake commissioner David Stern's hand. Getting an invitation to the Green Room is an honor in-and-of-itself, as only the top 12-16 prospects are invited in an effort to avoid the awkwardness of a player sitting alone, waiting to hear his name called.
