Mark DeLeone

Inside Linebackers


Mark DeLeone enters his 10th season as an NFL coach and first as the Detroit Lions' inside linebackers coach in 2021.

DeLeone spent the past two seasons (2019-20) as the inside linebackers coach for the Chicago Bears. In his two seasons in Chicago, the Bears allowed the sixth-fewest points (668) and tied for the fourth-fewest touchdowns allowed (74). He helped develop LB Roquan Smith, the eighth overall pick of the 2018 NFL Draft, to Second-Team AP All-Pro honors in 2020. Smith produced 100-tackle seasons in both years under DeLeone's tutelage.
