Kind of a fun article. http://fivethirtyeight.com/features/here-are-the-nfl-teams-that-play-the-highest-draft-picks/ Cliff notes- weights NFL teams rosters based on when their players were selected in the draft. The Bears are at the bottom for D and near the bottom on O. May be some injury effect since it weights based on actual snaps and we've had what high picks we have miss a lot of games. With that, each unit has just about average DVOA. Certainly IF Pace were to think about making a coaching change, still has a lot of work to get the talent level up. For as bad as Fox is, him and his staff does seem to coach guys up well. Our UDFA defensive backfield being a good example.
