full_context: Document 1: 1999 NBA draft: The 1999 NBA Draft was held on June 30, 1999, at the MCI Center (now Verizon Center) in Washington, D.C. It was the first draft in which four players from the same college were picked in the first round, with Elton Brand (1st selection), Trajan Langdon (11th), Corey Maggette (13th) and William Avery (14th) being selected out of Duke University. It is widely viewed as one of the best draft classes, with a total of nine future NBA All-Stars being chosen, as well as three winners of the NBA Sixth Man of the Year Award—Manu Ginóbili, Jason Terry, and Lamar Odom. Undrafted Pablo Prigioni made his NBA debut at 2012/2013 season as the oldest rookie in league history, at age 35.
Document 2: List of Illinois Fighting Illini in the NBA draft: The Illinois Fighting Illini men's basketball team, representing the University of Illinois at Urbana–Champaign, has had 68 players drafted into the National Basketball Association (NBA) since the league began holding the yearly event in 1947. Each NBA franchise seeks to add new players through an annual draft. The NBA uses a draft lottery to determine the first three picks of the NBA draft; the 14 teams that did not make the playoffs the previous year are eligible to participate. After the first three picks are decided, the rest of the teams pick in reverse order of their win–loss record.

Document 3: NBA high school draftees: The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school without playing basketball at the collegiate level. The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (especially overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Satnam Singh Bhamara, or even hold themselves back a year in high school before declaring for the draft, such as the case with Thon Maker.
