10 potenital defensive coordinators for Chicago Bears

4. Mark DeLeone

DeLeone is a potential in-house hire. He spent 2013-2018 with the Chiefs and has been in Chicago in 2019 and 2020.

Pros: Matt Nagy has worked with him dating back to 2013. The two have come up together. It may not be pro for some, but Nagy would likely want to see him get a shot. DeLeone would also be able to step in and not change much. He could improve on what Pagano brought, but keep things simple without drastic overhaul.

Cons: The inside linebackers were an issue this season. In 2019, Roquan Smith struggled to call plays and they had to bring back Trevathan because they were unsure he could take that step. Smith has insane stats but was not first-team All-Pro because running backs had their way with the inside linebackers. Hard to say he coached himself into a promotion.
