That's fair but if we are just talking about Defense, which is what I believed this conversation to be, then the Vikings accomplished much more, on three different occasion, then your 85 Bears team. Bears never had a defense that held opponents to under 10 points a contest. 11.7 is the best that defense ever produced. I would be interested in seeing who believes the Bears are the 2nd best team in NFL history. In my mind, they are not even close. As to the Sack totals, that's a straw man argument. 1st of all, the NFL didn't officially start keeping Sack statistics until 1982. Secondly, defenses got way more chances to get sacks in the 80s then in the late 60s/70s because there were more games and more pass attempts. You really can't say what the defenses did or did not accomplish, based on those two things.
