The 1987 NBA Finals was the championship round of the National Basketball Association (NBA)'s 1986–87 season, and the culmination of the season's playoffs. The Western Conference champion Los Angeles Lakers defeated the Eastern Conference and defending NBA champion Boston Celtics 4 games to 2. The key moment of the series was Magic Johnson's Junior sky hook in Game 4. This was the tenth time that the Celtics and Lakers met in the NBA Finals (more than any other Finals matchup). It would be the Celtics' last Finals appearance until the two teams met in 2008. This was the first NBA Championship Series conducted entirely in June. The last time there were no NBA Championship Series games in May was in the 1970–1971 season, when the finals (a four-game sweep that year) ended on April 30. It is also the first NBA Finals series to be conducted on a Sunday-Tuesday-Thursday rotation, which was in use until 1990 and revived since the 2004 NBA Finals; in between the NBA Finals were conducted on a Sunday-Wednesday-Friday rotation. Background Boston Celtics Thanks to the 1984 trade of Gerald Henderson and the subsequent fall of the Seattle SuperSonics, at the end of 1985–86 the Celtics were not only the best team in the NBA but also owned the second pick in the 1986 NBA Draft. They chose Len Bias with the pick and had high hopes that the presence of the young Maryland Terrapins star would ensure that the franchise would remain a powerhouse after Bird, McHale, and Parish retired. Unfortunately, Bias died 48 hours after being drafted, after using cocaine at a party and overdosing. The Celtics finished the regular season with a 59–23 record, best in the Eastern Conference. Despite retaining the core of the team that won the championship a year earlier, Boston endured numerous injuries to its roster. Their bench, an asset of the previous year's team, was decimated by injuries to Scott Wedman and Bill Walton. With limited options, head coach K. C. Jones was forced to give his starting five of Larry Bird, Kevin McHale, Robert Parish, Dennis Johnson and Danny Ainge extended minutes, but the lengthy playing time took its toll on the players' health, and by the start of the playoffs, the Celtics were a roster full of walking wounded. After sweeping the Chicago Bulls in the first round, the Celtics were pushed to a Game 7
