1990 NBA playoffs


The 1990 NBA playoffs was the postseason tournament of the National Basketball Association's 1989–90 season. The tournament concluded with the Eastern Conference champion Detroit Pistons defeating the Western Conference champion Portland Trail Blazers 4 games to 1 in the NBA Finals. Isiah Thomas was named NBA Finals MVP.
It was the Blazers' first trip to the NBA Finals since their victory in the 1977 NBA Finals.
The New York Knicks fell behind 2–0 to the Boston Celtics in their first round matchup, but took the series 3–2 by winning Game 5 121-114 in Boston Garden. Prior to this, the Celtics had beaten the Knicks 26 straight at the Boston Garden. This deciding game featured a missed dunk by Larry Bird late in the fourth with the Celtics trailing by four and a clinching 3-point basket by Patrick Ewing on a play where he chased down an errant pass by Charles Oakley on the sideline in front of the Knicks' bench and hurled up a desperation shot as the shot clock was reaching zero. The basket put the Knicks up 113-101 and essentially clinched the game and the series.
The Phoenix Suns defeated the Los Angeles Lakers in a playoff series for the first time ever. It also marked the first time since 1981 that the Lakers failed to reach the Western Conference Finals, ending the longest such run since the Bill Russell-led Boston Celtics, who made the Eastern Conference Finals thirteen consecutive times between 1957 and 1969.
It was the first NBA Finals to not feature the Lakers or Celtics since 1979.
The Chicago Bulls lost Game 7 of the Eastern Conference Finals 93–74 in Detroit, making it the third straight year they were ousted in the playoffs by the Pistons.
The Indiana Pacers made only their third playoff appearance since their NBA debut in the 1976–77 season; they proceeded to make the playoffs 16 out of the next 17 years.
The Dallas Mavericks made their only playoff appearance of the decade. They did not return until 2001.
Game 5 of the NBA Finals was the last NBA game to be televised on CBS.
