1984 NBA draft
The 1984 NBA draft was the 37th annual draft of the National Basketball Association (NBA). It was held at the Felt Forum at Madison Square Garden in New York City, New York, on June 19, 1984, before the 1984–85 season. The draft is generally considered to be one of the greatest in NBA history, with four Hall of Famers being drafted in the first sixteen picks and five overall. It included Michael Jordan, Charles Barkley, John Stockton and Akeem Olajuwon who was picked first. The draft was broadcast in the United States on the USA Network. In this draft, 23 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. The Houston Rockets won the coin flip and were awarded the first overall pick, while the Portland Trail Blazers, who obtained the Indiana Pacers' first-round pick in a trade, were awarded the second pick. The remaining first-round picks and the subsequent rounds were assigned to teams in reverse order of their win–loss record in the previous season. The Cleveland Cavaliers were awarded an extra first-round draft pick as compensation for the draft picks traded away by their previous owner, Ted Stepien. A player who had finished his four-year college eligibility was automatically eligible for selection. Before the draft, five college underclassmen announced that they would leave college early and would be eligible for selection. Prior to the draft, the San Diego Clippers relocated to Los Angeles and became the Los Angeles Clippers. The draft consisted of 10 rounds comprising the selection of 228 players. This draft was the last to be held before the creation of the draft lottery in 1985. It was also the first NBA draft to be overseen by David Stern, who would continue as the commissioner of the league for the following 30 years.
