The Baltimore Ravens struggled early on to find consistency on defense, and it wasn’t until Zach Orr made multiple moves with personnel that that unit started to produce. After watching Trenton Simpson regress in his first year as a starter, the Ravens are parting ways with inside linebackers coach Mark DeLeone Aaron Wilson reports.
#Ravens have moved on from inside linebackers coach Mark DeLeone, per league sources. DeLeone coached Roquan Smith in Baltimore this past season, and previously with #Bears @KPRC2

DeLeone joined the staff last February after head coach John Harbaugh and first-year Defensive Coordinator Zach Orr had to fill three vacancies on his staff after he was promoted and the departures of Anthony Weaver (Miami Dolphins defensive coordinator) and Dennard Wilson (Tennessee Titans defensive coordinator). Assistant Offensive Line Coach Mike Devlin went to the Los Angeles Chargers.
DeLeone, 36, has 17 years of coaching experience, most recently as a defensive analyst with the University of Kansas for the past two seasons. Before that, he spent 10 seasons (2012-2021) coaching in the NFL with the Detroit Lions (2021), Chicago Bears (2019-2020), Kansas City Chiefs (2013-2018), and New York Jets (2012).
He was the inside linebackers coach for the Chiefs, Bears, and Lions from 2018-2021. That included two seasons working with Ravens linebacker Roquan Smith in Chicago, where DeLeone helped Smith establish himself in the NFL and earn second-team All-Pro honors in 2020.
A University of Iowa graduate, DeLeone started coaching as a defensive student assistant under head coach Kirk Ferentz in 2007.
