Mike Macdonald enters his first season as the team's linebackers coach. Now in his fifth year with the Ravens, Macdonald previously spent time as the team's defensive backs coach (2017) and as a defensive assistant (2015-16). He originally joined Baltimore in 2014 as a defensive coaching intern. In 2017, alongside secondary coach Chris Hewitt, Macdonald helped guide a defensive backfield that contributed to the NFL's most INTs (22) and forced turnovers (34). In 2016, Macdonald worked with then-secondary coach and current Bills' defensive coordinator Leslie Frazier, helping guide a unit that finished seventh overall (322.1 ypg) and produced a league-leading (tied, KC & SD) 18 interceptions. During the 2015 campaign, Macdonald worked closely with defensive coordinator (then-inside linebackers coach) Don Martindale. Macdonald was a graduate assistant at Georgia (2011-13) while earning his master's in sports management.
