The 1980 NBA World Championship Series was the championship round of the 1979–80 NBA season.

Kareem Abdul-Jabbar was the league's MVP. But midway through Game 5, the Laker center suffered a severely sprained ankle. He managed to come back in the game in the 4th quarter to lead the Lakers to victory and a 3-2 lead in the best-of-seven series. But the Lakers still had to travel to Philadelphia for Game 6. Abdul-Jabbar was listed as out of game 6, although 76er coach Billy Cunningham was quoted as saying "I won't believe he's not playing until their plane lands and he's not on it." As it turned out, Kareem did not make the trip and was listed as doubtful if Game 7 had been needed.

In game 6, Magic Johnson played what may have been the greatest game of his career. Playing on the road in Philadelphia, Magic (a 6'9" point guard) started the game at center and eventually played all 5 positions in a dominating performance. Scoring a game-high 42 points and grabbing a game-high 15 rebounds—and handing out 7 assists—Magic Johnson led the Lakers to the NBA crown. The Lakers also received strong performances from Jamaal Wilkes with 37 points, and Norm Nixon. Jim Chones played strong defense on 76er center Darryl Dawkins, while Mark Landsberger provided rebounding off the bench, and little used Brad Holland chipped in 8 key points.

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.

Earvin "Magic" Johnson Jr. (born August 14, 1959) is a retired American professional basketball player who played point guard for the Los Angeles Lakers of the National Basketball Association (NBA). After winning championships in high school and college, Johnson was selected first overall in the 1979 NBA Draft by the Lakers. He won a championship and an NBA Finals Most Valuable Player Award in his rookie season, and won four more championships with the Lakers during the 1980s. Johnson retired abruptly in 1991 after announcing that he had contracted HIV, but returned to play in the 1992 All-Star Game, winning the All-Star MVP Award. After protests from his fellow players, he retired again for four years, but returned in 1996, at age 36, to play 32 games for the Lakers before retiring for the third and final time.

Johnson's career achievements include three NBA MVP Awards, nine NBA Finals appearances, twelve All-Star games, and ten All-NBA First and Second Team nominations. He led the league in regular-season assists four times, and is the NBA's all-time leader in average assists per game, at 11.2. Johnson was a member of the "Dream Team", the U.S. basketball team that won the Olympic gold medal in 1992.

Julius Winfield Erving II (born February 22, 1950), commonly known by the nickname Dr. J, is a retired American basketball player who helped launch a modern style of play that emphasizes leaping and play above the rim. Erving helped legitimize the American Basketball Association (ABA). He was the best known player in the ABA when the ABA-NBA merger joined it with the National Basketball Association (NBA) after the 1976 season.

Erving won three championships, four Most Valuable Player Awards, and three scoring titles while playing with the ABA's Virginia Squires and New York Nets, and the NBA's Philadelphia 76ers. He is the fifth-highest scorer in professional basketball history, with 30,026 points (NBA and ABA combined). He was well known for slam dunking from the free throw line in Slam Dunk Contests and was the only player to have been voted Most Valuable Player in both the ABA and the NBA.

Erving was named to the NBA's 50th Anniversary All-Time team and in 1993 was inducted into the Basketball Hall of Fame. In 2004, he was inducted into the Nassau County Sports Hall of Fame. Many consider him among the most spectacular basketballers ever, and one of the best dunkers of all time. While players such as Connie Hawkins, "Jumping" Johnny Green, Elgin Baylor, and Gus Johnson were performing spectacular dunks before Erving's time, "Dr. J" is usually the one most people credit with bringing the practice into the mainstream. His signature dunk was the "slam" dunk, since incorporated into the vernacular and basic skill set of the game, in the same manner as the "cross-over" dribble and the "no look" pass.
