The 1999–2000 NBA season was the 12th season for the Miami Heat in the National Basketball Association. During the off-season, the Heat signed free agents Otis Thorpe, and undrafted rookie guard Anthony Carter. The Heat played the first two months of the season at the Miami Arena. They played their final home game at the Miami Arena on December 28, 1999, against the Minnesota Timberwolves, and then moved into the American Airlines Arena on January 2, 2000, against the Orlando Magic. The Heat got off to a 15–4 start, then later on holding a 30–17 record at the All-Star break. However, Tim Hardaway only played 52 games due to knee injuries, and Voshon Lenard was out for the remainder of the season with a lower abdominal strain after 53 games. At mid-season, the team signed free agent Bruce Bowen. The Heat went on a 7-game winning streak between March and April, and finished first place in the Atlantic Division with a 52–30 record. Alonzo Mourning averaged 21.7 points, 9.5 rebounds and 3.7 blocks per game, and was named Defensive Player of the Year for the second consecutive year. He was also named to the All-NBA Second Team, NBA All-Defensive First Team, was selected for the 2000 NBA All-Star Game, and finished in third place in Most Valuable Player voting behind Shaquille O'Neal and Kevin Garnett. In addition, Jamal Mashburn averaged 17.5 points and 5.0 rebounds per game, while Hardaway provided the team with 13.4 points and 7.4 assists per game, Lenard contributed 11.9 points per game off the bench as the team's sixth man, and P.J. Brown provided with 9.6 points and 7.5 rebounds per game. Three-point specialist Dan Majerle contributed 7.3 points and 1.3 steals per game, while Clarence Weatherspoon averaged 7.2 points and 5.8 rebounds per game off the bench, and Carter provided with 6.3 points, 4.8 assists and 1.2 steals per game. In the Eastern Conference First Round of the playoffs, the Heat swept the Detroit Pistons in three straight games, en route to advancing to the second round for the first time since 1997. In the Eastern Conference Semi-finals, they faced the New York Knicks for the fourth consecutive year. After taking a 3–2 series lead, the Heat would lose the final two games to the 3rd-seeded Knicks, including an 83–82 loss in Game 7 in Miami. Following the season, Mashburn, Brown and Thrope were all traded to the Charlotte Hornets, while Lenard and Mark Strickland were both traded to the Denver Nuggets, and Weatherspoon was dealt to the Cleveland Cavaliers in a three-team trade. For the season, the Heat changed their primary logo adding a darker red color to the flaming basketball, and added new uniforms with side panels to their jerseys and shorts. The uniforms remained in use until 2009, where they switched the logo to the other leg of their shorts, while the primary logo is still present as of 2023.
