The 1974 NBA World Championship Series was the championship round of the 1973-74 NBA season.

Celtics win series 4-3

Before the series started, Bucks point guard Lucius Allen would be lost for the series with a knee injury. In Game 1, the Celtics took advantage, harassing a 35-year old Oscar Robertson and Allen's replacement, Ron Williams, into frequent turnovers. The Celtics took a 35-19 lead in the first quarter and never looked back on the way to a 98-83 win in Milwaukee. Kareem Abdul-Jabbar scored 35 points for the Bucks.

Kareem Abdul-Jabbar scored 36 points, but more importantly, he took more of a role in running the Bucks' offense from the post, given their backcourt issues. His passing enabled Bob Dandridge to score 24 points.

On the defensive end, Abdul-Jabbar forced Dave Cowens into shooting 3-of-13 from the floor, including a block of a Cowens shot at the end of regulation to force overtime. The Bucks won in overtime, 105-96, to even the series at a game apiece as it headed to Boston.

The NBA Finals is the championship series of the NBA. The series was named the NBA World Championship Series until 1986.

The series is played between the winners of Western Conference Finals and Eastern Conference Finals. At the conclusion of the championship round, the winners of the NBA Finals are awarded the Larry O'Brien Championship Trophy. (Winners from 1946 to 1977 received the Walter A. Brown Trophy) The NBA Finals has been played at the conclusion of every NBA and BAA season in history, the first being held in 1947.

Since 1985, the winner of the NBA Finals has been determined through a 2–3–2 format. The first two and the last two games of the series are played at the arena of the team who earned home court advantage by having the better record during the regular season.

During the first decade the Minneapolis Lakers had the first NBA dynasty, winning 5 championships in 6 years under Hall of Fame head coach John Kundla. The team also featured George Mikan, one of the greatest players in the history of the NBA. Franchises which had previously been in the National Basketball League tended to dominate, especially the Minneapolis Lakers.

John J. "Hondo" Havlicek (pronounced /ˈhævlɨtʃɛk/ HAV-lə-chek; born April 8, 1940 in Martins Ferry, Ohio) is a retired American professional basketball player who competed for 16 seasons with the Boston Celtics, winning eight NBA titles, half of them coming in his first four seasons.

In the NBA, only teammates Bill Russell and Sam Jones won more championships during their playing careers. Havlicek is considered one of the best NBA players in history, especially on defense, and was inducted as a member of the Naismith Memorial Basketball Hall of Fame in 1984. He was a three sport star at Bridgeport High School in Bridgeport, Ohio and one of his boyhood friends was Baseball Hall of Fame pitcher Phil Niekro. The Bridgeport High School Gymnasium was renamed the "John J Havlicek Gymnasium" in January 2007. He shares the honor with National High School Hall of Fame member Frank Baxter, a long time coach at Bridgeport High School. The court is named after Baxter.

One of the most famous play-by-play calls in NBA history came on April 15, 1965, when Celtics broadcaster Johnny Most exclaimed "Havlicek steals it! Havlicek stole the ball!" after Havlicek intercepted Hal Greer's inbound pass to clinch the Eastern Conference Championship against the Philadelphia 76ers.

Kareem Abdul-Jabbar (born Ferdinand Lewis Alcindor, Jr., April 16, 1947) is a retired American professional basketball player. He is the NBA’s all-time leading scorer, with 38,387 points. During his career with the NBA’s Milwaukee Bucks and Los Angeles Lakers from 1969 to 1989, Abdul-Jabbar won six NBA championships and a record six regular season MVP Awards. In college at UCLA, he played on three consecutive national championship teams, and his high school team won 71 consecutive games. At the time of his retirement, Abdul-Jabbar was the NBA’s all-time leader in points scored, games played, minutes played, field goals made, field goal attempts, blocked shots, defensive rebounds, and personal fouls. Abdul-Jabbar also has been an actor, basketball coach and an author. In 2012, he was selected as a U.S. cultural ambassador.

Abdul-Jabbar was born Ferdinand Lewis Alcindor, Jr., on April 16, 1947, and grew up in Manhattan in New York City, the only child of Cora Lillian, a department store price checker, and Ferdinand Lewis Alcindor, Sr., a transit police officer and jazz musician. At birth, he weighed 12 pounds, 10 ounces (5.73 kg), and was twenty-two-and-a-half inches (57.2 cm) long. He was raised as a Roman Catholic and attended St. Jude School in the Inwood section of Manhattan. Later in life, he converted to Islam. He initially joined the Nation of Islam in 1968, before retaking the Shahada and converting to Sunni Islam that same summer.

Robert Lee "Bob" Pettit Jr. (born December 12, 1932, in Baton Rouge, Louisiana, U.S.) is a retired American professional basketball player. He played 11 seasons in the NBA, all with the Milwaukee/St. Louis Hawks (1954-1965). He was the first recipient of the NBA's Most Valuable Player Award. He was inducted into the Naismith Memorial Basketball Hall of Fame in 1970. He also went by the nickname "Dutch" in college. He also won the NBA All-Star MVP award four times.

Pettit's basketball career had humble beginnings. At Baton Rouge High School, he was cut from the varsity basketball team as both a freshman and sophomore. His father, Sheriff of East Baton Rouge Parish (1932-1936), pushed him to practice in the backyard of the Kemmerly house until he improved his skills. It worked: Pettit became a starter as a junior, and led Baton Rouge High to its first State Championship in over 20 years in his senior year.

After high school, Pettit accepted a scholarship to play at Louisiana State University. He was a three-time All-Southeastern Conference selection and a two-time All American as a member of the LSU men's basketball team. (Freshmen were not allowed to play varsity basketball in those days.) During those three years, Pettit averaged 27.8 points per game. He was also a member of the Zeta Zeta Chapter of Delta Kappa Epsilon at LSU.
