High Quality Content by WIKIPEDIA articles! The 1999 NBA Playoffs was the postseason tournament of the National Basketball Association`s 1998-99 season. The tournament concluded with the Western Conference champion San Antonio Spurs by defeating the eighth-seeded Eastern Conference champion New York Knicks four games to one. The 1999 playoffs are memorable for the fact that a number eight seed made it to the Finals for the only time in history, as well as the fact that it came after a lockout-shortened fifty game season. This would also be the first time in which two teams would play each other on a back to back night in playoff history.
