96-97 Packers and the Broncos teams that followed were both dominant football teams on both sides of the ball as well. I can't count the 2000 Ravens or 2002 Buccs because both of those teams were only dominant on Defense with very mediocre offenses. They wouldn't be able to hang with some of the all time greats that were built up on both sides of the ball like the Cowboys, Niners, Packers, and Broncos
