It may or may not carry over. Preseason record doesn't tell us one way or the other. And your example hardly applies considering the Bears are 2-1. That was just an example showing that preseason play doesnt mean anything. If you go off the assumption that you have to be playing "well" to go 4-0 in the preseason, it means nothing with regards to the regular season success of the team. As far as individual units, how much can you really take out of watching the defensive line going vanilla with no gameplan tailored to the opponent? No disguises, little blitzing, etc. Or the offensive line...are they coming up with a game plan to handle the other team's best pass rusher, or are they hiding that plan so that other teams with elite pass rushers don't have tape on it? And then you consider the fact that as much as the players want to to play as hard as they can, unless you are fighting for a spot on the team or a starting role the intensity is not 100%, not for the opponents, not for the Bears. So you have Bears players playing at 85% running very basic plays out of very basic formations going against a team that is also playing at 85% running very basic plays and this is supposed to tell you anything about the regular season?
