The 1970 NBA draft was the 24th annual draft of the National Basketball Association (NBA). The draft was held on March 23, 1970, before the 1970–71 season. In this draft, 17 NBA teams took turns selecting amateur U.S. college basketball players and other eligible players, including international players. A player who had finished his four-year college eligibility was eligible for selection. If a player left college early, he would not be eligible for selection until his college class graduated. The first two picks in the draft belonged to the teams that finished last in each division, with the order determined by a coin flip. The Detroit Pistons won the coin flip and were awarded the first overall pick, while the San Diego Rockets 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. Three expansion franchises, the Buffalo Braves, the Cleveland Cavaliers and the Portland Trail Blazers, took part in the NBA Draft for the first time and were assigned the seventh, the eighth and the ninth pick in each round. In the first round, the Cavaliers had the seventh pick, while the Blazers and the Braves had the eighth and the ninth pick respectively. In the subsequent rounds, the Cavaliers and the Braves exchanged their order of selection, while the Blazers had the eighth pick throughout the draft. The draft consisted of 19 rounds comprising the selection of 239 players; it holds the record for the most prospects selected in any NBA draft.
