I recently looked at the history of teams to make a significant improvement from one year to the next and found that many of them win fewer games the year after their breakthrough season. This suggests that the Bears might be due for a bit of a letdown from their 12-4 record in 2018 (though they do match the profile of teams that generally stay good after making the jump.)
Today, I want to look more closely at Chicago’s underlying performance in 2018 to see if there’s anything there to suggest they are a team poised for a fall.
