Obviously the Bulls were top. The Pistons were great in the early 90s. The Jazz were great. The Rockets were obviously very good mid-90s. The Blazers were very good. The Spurs were great to end the decade. A few other teams had flashes. (Should we include Reggie Miller's Pacers... ?). The Knicks were very good but I don't remember them as a team anyone expected to win. Maybe my memory is bad.
The Sonics won a lot of games too...
