Decade overview
1990s NBA champions
Four franchises won in the 1990s. Michael Jordan's Bulls took six titles, Hakeem Olajuwon won two, and the decade opened and closed with Detroit and San Antonio.
Chicago won six championships (1991 through 1993, then 1996 through 1998). Houston won back-to-back in 1994 and 1995. Detroit won in 1990. San Antonio won in 1999. Four franchises total.
Michael Jordan and Scottie Pippen defined the middle of the decade. Hakeem Olajuwon carried Houston through the two seasons Jordan left the league. Isiah Thomas and the Bad Boys won Detroit's last title in 1990. David Robinson and Tim Duncan closed the decade in San Antonio.
Jordan's Bulls ran the triangle offense through isolation and structured movement. Houston played through Olajuwon in the post with shooters around him. Detroit's early-1990s teams still played bruising defense. By the late 1990s, pace slowed and half-court execution mattered more than transition.
