Chicago’s offense was generally mediocre in 2018. We all know this. They finished 21st in the NFL in yards per game, 9th in points scored (a number buoyed by a bunch of defensive touchdowns), and 20th in Football Outsiders’ DVOA. Those types of basic stats are easy for anybody to look up, and they can help paint an overall picture of how effective a unit performed.
They do not, however, tell a complete tale.
It can be useful to look deeper and see in what areas the Bears might have struggled, as well as where they might have done well.
