Who was the head coach during the 1999 season in which Ben Wallace was traded from the Washington Wizards?
1999–2000 Orlando Magic season The 1999–2000 NBA season was the 11th season for the Orlando Magic in the National Basketball Association. During the offseason, the Magic hired Doc Rivers as Head Coach while acquiring Tariq Abdul-Wahad from the Sacramento Kings, Chris Gatling from the Milwaukee Bucks, Ben Wallace from the Washington Wizards, second-year forward Pat Garrity from the Phoenix Suns, and rookie Corey Maggette from the Seattle SuperSonics, while signing free agents John Amaechi and Monty Williams. The Magic's transition continued at midseason, trading Abdul-Wahad and Gatling to the Denver Nuggets for Ron Mercer, Chauncey Billups and Johnny Taylor. However, Billups never played for the Magic due to a shoulder injury he sustained in Denver.
1998–99 Miami Heat season The 1998–99 NBA season was the 11th season for the Miami Heat in the National Basketball Association. During the offseason, the Heat signed free agents Terry Porter and Clarence Weatherspoon. In the shortened NBA season, the Heat won 18 of their first 23 games, despite Jamal Mashburn playing just 24 games due to a knee injury, and Voshon Lenard missing 38 games with a broken leg. Miami finished with a 33–17 win-loss record, which earned them the #1 seed in the Eastern Conference. Alonzo Mourning was named Defensive Player of the Year, and finished second in MVP voting behind Karl Malone of the Utah Jazz.
