I know I'm basically pissing in the ocean here, but the '85 Bears defense kinda sucks as an analogy any time it's used.
The '85 Bears defense's front 7 were obviously amazing, but what really made it dominant was a short-term schematic advantage; most NFL offenses ran play-action, runs setting up deep passes. So the Bears put 8 in the box and blitzed like crazy. Yes, their front 7 was amazing, but their DBs were dubious; the one time they played a team that could throw and throw well, they got punked, and only dodged them in the Super Bowl because the Patriots ran 9,243 times against the Dolphins in the AFC Title Game and the Fins couldn't stop 'em. In 1986, it was Washington gettin' 186 yards on 32 pass attempts -- a huge number of attempts for the time -- that ended Chicago's playoff run in its first game. (Also, in '86, McMahon pulled a Manziel, and pretty much was never good again, which didn't help.)
In other words, I put more stake in NFL offenses being dumb than in the Bears' defense being all that good.
actually now that I think of it the Bears-Dolphins game is a lot like our semifinals loss against Washington but I'd really rather not talk or think about that right now
