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. Draft selections and draftee career notes Bob Lanier from St. Bonaventure University was selected first overall by the Detroit Pistons. Rudy Tomjanovich from the University of Michigan and Pete Maravich from Louisiana State University were selected second and third respectively. Fourth pick Dave Cowens from Florida State University and eighth pick Geoff Petrie from Princeton University went on to be named as joint winners of the Rookie of the Year Award in their first season. Six players from this draft, Lanier, Maravich, Cowens, 18th pick Calvin Murphy, 19th pick Nate Archibald and 122nd pick Dan Issel, have been inducted to the Basketball Hall of Fame. Maravich, Cowens and Archibald were also named to the list of the 50 Greatest Players in NBA History announced at the league's 50th anniversary in 1996. Maravich had four All-NBA Team selections and
