to make some sense from the 76ers' perspective. Chamberlain was making noises about jumping to the American Basketball Association, and general manager Jack Ramsay did not want to risk letting Chamberlain walk away for nothing. Nonetheless, the Sixers did not get nearly enough in return. The man who was in position to take over as the center, Lucious Jackson, suffered a severe injury in 1969 and was never the same player after that. The Chamberlain trade sent the Sixers into a freefall, which Ramsay accelerated by subsequent divestiture of All Star forward Chet Walker to the Chicago Bulls. While the rapidly declining 76ers continued to contend for the next three seasons, they never got past the second round. In 1971–72, only five years after winning the title, the 76ers finished 30–52 and missed postseason play for the first time in franchise history. The bottom fell out in the 1972–73 season. For all intents and purposes, the season ended when Cunningham bolted to the ABA, leaving the Sixers with a roster of Greer and little else. The 76ers lost their first 15 games of the season, and a few months later set a then-record 20-game losing streak in a single season. Their record following the 20-game losing streak was 4–58, and the team at that point had just lost 34 of 35 games. The 76ers finished the season with a 9–73 record, leading the skeptical Philadelphia press to call them the "Nine and 73-ers". Under coach Roy Rubin the 76ers went 4–47. It was his first and, as it turned out, his last NBA coaching job. He was succeeded by player-coach Kevin Loughery, who went 5–26 the rest of the way. The 76ers finished an NBA-record 59 games behind the Atlantic Division champion Boston Celtics. The nine wins by the 1972–73 squad is the fourth-fewest in NBA history, and remains the fewest for a full 82-game season. The 73 losses, although threatened several times, remains the all-time low-water mark for any NBA franchise. The 76ers’ 0.110 winning percentage was a record worst at the time, and would remain the lowest until the 2011–12 Charlotte Bobcats finished 7–59 for a .106 winning percentage in a season shortened due to a lockout. Only six seasons earlier, the 76ers had set the NBA record for most wins in a season. The 76ers of 1972–73 are generally considered to be the worst team ever to
