Michael Jordan entered the league in 1984 with the Chicago Bulls , providing an even more popular star to support growing interest in the league. This resulted in more cities demanding teams of their own. In 1988 and 1989, four cities got their wishes as the Charlotte Hornets , Miami Heat , Orlando Magic , and Minnesota Timberwolves made their NBA debuts, bringing the total to 27 teams. In the first year of the 1990s, the Detroit Pistons would win the second of their back-to-back titles, led by coach Chuck Daly and guard Isiah Thomas . Jordan and Scottie Pippen would lead the Bulls to two three-peats in eight years during the 1991–98 seasons. Hakeem Olajuwon won back-to-back titles with the Houston Rockets in 1994 and 1995.
