Biography

Mark DeLeone enters his fifth campaign with the Kansas City Chiefs, and third as assistant linebackers coach in 2017. Before being promoted, DeLeone was a defensive quality control coach for three seasons, two with the Chiefs (2013-14) and one with the New York Jets (2012). DeLeone's time in Kansas City is highlighted by tutoring linebackers to a Pro Bowl berth in his first four seasons with the Chiefs.

Under DeLeone’s guidance, LBs Derrick Johnson and Ramik Wilson ranked first and third on the roster in tackles with 90 and 76, respectively. Johnson has registered 801 tackles in eight seasons, becoming the Chiefs all-time leader in tackles in 2016 racking up 1,191 tackles since his rookie season in 2005. Dee Ford had a career-best 10.0 sacks on the season which led the Chiefs defense, while Justin Houston (4.0) and Tamba Hali (3.5) followed behind to finish second and third on the roster. Additionally, LB D.J. Alexander was selected to the Pro Bowl as an alternate.

DeLeone's third season with the Chiefs saw Tamba Hali, Justin Houston and Derrick Johnson all earn Pro Bowl berths, just the third time in franchise history that three Chiefs linebackers were selected to the NFL's all-star game, with all three occurences being held by Hali, Houston and Johnson.

In his second season, Houston broke the team’s franchise record for sacks with 22.0, topping Derrick Thomas’ previous record of 20.0 sacks in a single season. Houston’s performance led to him being named the Derrick Thomas award winner as the team’s MVP. 

Prior to entering the NFL coaching ranks with the Jets in 2012, DeLeone served as a graduate assistant at Temple University during 2011. He also served as a quality control coach at the University of Florida in 2010, working on Head Coach Urban Meyer’s staff.

He worked with the wide receivers in the spring, and then moved on and worked with the offensive line and tight ends in the fall. During that season, the Gators produced seven All-SEC performers en route to their Outback Bowl victory.

In 2009, he held the titles of director of football operations and assistant offensive line coach at the University of New Hampshire. In that season, the Wildcats went 10-3 en route to the Colonial Athletic Association North championship and a quarterfinal showing in the Football Championship Subdivision playoffs.

He began his collegiate coaching career at the University of Iowa, where he was a defensive student assistant for Head Coach Kirk Ferentz and the Hawkeyes staff (2007-08). In 2007, he worked with the linebackers and switched to the defensive line in 2008. While with the Hawkeyes, Iowa won the 2009 Outback Bowl and produced 14 All-Big Ten selections and 22 NFL players.

DeLeone worked with two 2011 first-round NFL Draft picks in OL Mike Pouncey (Florida) and Adrian Clayborn (Iowa) during his time in the collegiate coaching ranks.

A 2009 graduate of the University of Iowa, DeLeone earned a bachelor’s degree in liberal arts and sciences.
