85 Bears had the greatest DEFENSE. Offense was just good enough.

They had a great offensive line and the best running back of all time. The rest of their offense was good enough to win games.

The 1984 49ers may have been the best team of the 1980s. Dominant offensive team (and Jerry Rice hadn't even been drafted yet!) and a very underrated defense. I think they are still the only NFL team in history to send all four of their starting defensive backs to the Pro Bowl.
