You must be too young to remember 1985 because if you did remember it you would know that one of the best defenses in the history of the NFL was taken apart by that same one-dimensional offense you tout. The Bears were undefeated (12-0) until they ran into the Dolphins and their passing game. Marino's quick release nullified the Bears 46 defense and killer pass rush.
The Dolphins only ran for 90 yards but Marino passed for 270 and 3 TDs as Clayton, Duper, and Nat Moore each had over 75 yards receiving.
That Bears team went on to win the SB after going 15-1 in the regular season. This game was their only loss that year and it wasn't that the Bears played a bad game, it was just that the passing game of the Dolphins beat them.
There really wasn't much of a running game to keep th Bears defense honest yet it didn't matter.
