Atlantic

Buffalo supplanted New York as Boston's most serious rival in the Atlantic foursome with 49 wins. Buffalo boasted high-scoring super star Bob McAdoo. The Big Mac posted a 34.5 scoring average to lead the NBA, making more field goals than any other player. He also led in minutes played, while also ranking among the best rebounders and shot blockers in the league. The 6'10 220-pounder was threatening enough to also earn 798 free throw tries, another league high, converting a solid 81%. The Braves lost sensation Ernie DiGregorio to knee injury, watched former Laker Jim McMillian battle illness, and also lost Gar Heard for 25 games, which dropped the team from the elite and put more of the load on their star. This dimmed hopes for the playoffs.

This would be the high-water mark for the Braves franchise in Buffalo. The franchise left Buffalo to become the San Diego Clippers in 1978 and would not reach the 50-win mark until 2012–13, by which time the Clippers were in their 29th season in Los Angeles and 35th overall in Southern California.

Pacific

Golden State boasted the top-scoring offense in the league at 108.5 points per game to win the Pacific five and 48 games. Rick Barry turned in one of his greatest seasons ever to score 30.6 points per game, trying even more shots than McAdoo. Barry sank 90% of his free throws with his unique underhand delivery and finished sixth in the NBA in assists. But Barry may have shocked most by leading the NBA in steals as well, using surprisingly quick hands while playing passing lanes as well as any forward ever. Criticized in the past, Barry's season was such that many writers believed Barry, not Cowens, Hayes or McAdoo, to be the NBA's true MVP this year. The playoffs would tell more of that story.

Central

The Washington Bullets led by Elvin Hayes and Wes Unseld won 60 games, a tie with the Boston Celtics for first in the league and the Houston Rockets led by Calvin Murphy and Rudy Tomjanovich reached their first season at .500 as well as made the playoffs for the first time in Houston and second in franchise history.

Midwest

The Chicago Bulls won 47 games to capture their first-ever division title. As usual, Chicago did it with a stifling defense that began with guards Jerry Sloan and Norm Van Lier. Holdout Bob Love missed 20 games but again led in scoring while signee Nate Thurmond got into the defense at center. The 33-year-old gave the team a needed rebounder while ranking third in the NBA in blocked shots.

The defending Western Conference champion Milwaukee Bucks suffered a precipitous decline following the retirement of Oscar Robertson, dropping from 59 wins in '73–'74 to 38 in '74–'75. This would be the final season in Wisconsin for Kareem Abdul-Jabbar, who forced a blockbuster trade during the summer of 1975 to the Lakers.

With the Bucks in the doldrums, it fell to Kansas City–Omaha to challenge Chicago for division supremacy. Nate Archibald responded by averaging 26.5 points per game, while Sam Lacey was a force in the paint with 11.4 rebounds a contest.

Playoffs

Seven NBA teams out of 17 finished over .500, but three teams, New York, Cleveland and Detroit, also had 40–42 records. Boston drew a young 41–41 Houston team who had just won their first playoff series in franchise history against the Knicks 2–1. The Rockets had 20-point scorers Calvin Murphy and Rudy T. but little rebounding, and the veteran Celtics got past the Rockets 4–1 and into the Conference Finals once again. The much tougher East bracket was Washington, who had the same record Boston had, against the tough Buffalo Braves. Hayes vs. MacAdoo was the marquee matchup. But the Braves, who had traded Bob Kauffman, did not have the help for their star. Despite that, the series went the full seven in impressive fashion before the Bullets won to advance. Randy Smith played well in place of Ernie D, but not enough to turn the series the other way. Out West, Golden State, still under the radar with many, met a solid Seattle team. Spencer Haywood, the SuperSonics' outspoken star, struggled with illnesses much of this year. Rookie center Tom Burleson and bombing guard Fred Brown picked up Haywood's slack with 20-point averages from the passes of guard Slick Watts, their first defender. But a 124–100 wipeout loss in Game Five put the writing on the wall as the Warriors advanced. Chicago drew a very good Kansas City team that had bounced back from the bad Bob Cousy days under coach Phil Johnson. Nate Archibald was their star at just 5'11. But the Bulls guards hounded Nate the Skate to just 36% shooting in the series. Bob Love also schooled rookie forward Scott Wedman as the Bulls won 4–2. The anticipated monster clash of Boston-Washington was set, with DC native Red Auerbach in the shadows. Cowens and Hayes each turned in very strong performances, but did not guard each other. Havlicek and White joined Cowens as 20-point Celtic scorers. But somehow the Celtics lost three of the first four ballgames anyway. The inside defense of the Bullets, combined with plenty of free throws, allowed Washington to send the vaunted world champions home. For some, this was a title in itself. But there was still one more round to play. Most experts now expected Chicago to finally get their hard-earned shot in a classic offense vs. defense series against Golden State. Plus, Thurmond was seeking revenge against his old team, which now had 6'10 Cliff Ray, a former Bull and a lesser center, in his former Warrior center spot. The series would be a full seven-game barnburner. The Bulls used a 90–89 Game Two win to start a 2–1 advantage. Golden State bounced back to win Game 4 but the Bulls won Game 5, making it 3–2. The Warriors cranked it up to win Game Six 86–72 in Chicago to force Game Seven at home. Bulls coach, Dick Motta, was giving most of the center minutes to rebounder Tom Boerwinkle, not Thurmond. With no bench scoring and Thurmond playing an average of just 20 minutes per game, The Warriors wiggled off the hook to win the game 83–79 and the series, 4–3. It was a hard loss for Bulls fans who had pulled for their team all decade.

Finals

Washington-Golden State did not have the sizzle that Boston-Golden State would have had in the eyes of some. But then the Bullets, still glowing from their win over Boston, barely showed up anyway. The Warriors won Game 1 on the road 101–95, then won Games 2 and 3 at home, 92–91 and 109–101, respectively. Washington fans now expected the Bullets to come out blazing, and for Hayes and Unseld to take over the paint. Rookie Keith Wilkes, the local UCLA favorite, was quietly having a strong playoffs at power forward. He was listed at 6'7 and 190 pounds, and was opposite the 6'10 240-pound Hayes. Barry and Wilkes were the only Warriors scorers over 15 points per game in the series, and two Warriors starters averaged less than 10 points per game. However, Game 4 was a one-point win, 96–95, and the Warriors pulled a remarkable sweep to win the series 4–0.^[1] Wilt Chamberlain had never won the title as a Warrior center, but now Cliff Ray had in his first try. Rick Barry averaged 28 points to be the star, but coach Al Attles' team had hustled and sweated throughout to key one of the most unusual and impressive championships ever.
