The 1972–73 NBA season was to be Chamberlain's last, although he didn't know this at the time. In his last season, the Lakers lost substance: Happy Hairston was injured, Flynn Robinson and LeRoy Ellis had left, and veteran Jerry West struggled with injury. Chamberlain averaged 13.2 points and 18.6 rebounds, still enough to win the rebounding crown for the 11th time in his career. In addition, he shot an NBA record 0.727 for the season, bettering his own mark of 0.683 from the 1966–67 season. It was the ninth time Chamberlain would lead the league in field goal percentage. The Lakers won 60 games in the regular season and reached the 1973 NBA Finals against the New York Knicks. This time, the tables were turned: the Knicks now featured a healthy team with a rejuvenated Willis Reed, and the Lakers were now handicapped by several injuries. In that series, the Lakers won Game 1 115–112, but the Knicks won Games 2 and 3; things worsened when Jerry West injured his hamstring yet again. In Game 4, the shorthanded Lakers were no match for New York, and in Game 5, the valiant, but injured West and Hairston had miserable games, and despite Chamberlain scoring 23 points and grabbing 21 rebounds, the Lakers lost 102–93 and the series. After the Knicks finished off the close fifth game with a late flourish led by Earl Monroe and Phil Jackson, Chamberlain made a dunk with one second left, which turned out to be the last play of his NBA career.
