The 1965–66 NBA Season was the 20th season of the National Basketball Association. The season ended with the Boston Celtics winning an unprecedented 8th straight NBA Championship, beating the Los Angeles Lakers 4 games to 3 in the 1966 NBA Finals.
The season started out looking good for Philadelphia 76ers star Wilt Chamberlain, as he had a full year with his new team after half a season the year before. The Sixers came together behind him and won the NBA East with 55 wins in 80 NBA games, the top record in the league.
Yet again, Chamberlain himself was a dominant force. His 1074 field goals were more than 250 ahead of the next top shooting scorer in the league. His 976 free throws tried were second most in the league, helping his NBA-high scoring average even with all the misses at the foul line. He also led the league in shooting accuracy, rebounds and minutes played. He also was 7th in assists.
After the 76ers and Celtics, the nine-team NBA also featured two strong also-rans. The Los Angeles Lakers won 45 of 80 games to capture the West Division of the NBA, which produced no league champion 1959–1970. The Lakers were led by superstar Jerry West, whose 818 field goals made were tied for second most in the NBA. He also tried and made the most free throws in the league as he carried the Laker load, going 840 of 977 for an 86% clip. The Lakers' mediocre center play and more limping from Elgin Baylor held back the club's advancement.
The Cincinnati Royals won 45 games also, but were still stuck in the East Division behind the 76ers and Celtics while the Baltimore Bullets remained in the NBA West. The Royals were led again by Oscar Robertson and Jerry Lucas. Robertson matched West's 818 field goals made while also leading the NBA in assists. Robertson got a few more assists than West because he had Lucas to pass to. The Royals forward averaged 22 points and 21 rebounds per game for the season. West, Robertson, and Lucas accomplished their feats without the benefit of a three-point line.
