The Chargers announced on Wednesday that a number of additions have been made to Jim Harbaugh‘s staff. Many have already been reported, but others include a few notable names. 
Marc Trestman has been added as a senior offensive assistant. This marks his first NFL coaching opportunity since his run as offensive coordinator of the Ravens came to an end. Baltimore fired Trestman midway through the 2016 campaign, leading him to return to the Canadian Football League. Trestman coached the Toronto Argonauts in 2017-18, earning his second CFL Coach of the Year honor and third Grey Cup title in that span.
His return north of the border was followed by a one-year stint in the XFL as head coach of the Tampa Bay Vipers in 2020. Trestman has not coached since then, and he is far removed from his two-year run at the helm of the Bears. Still, the 68-year-old will offer considerable experience on the offensive side of the ball as the Chargers transition to a unit led by Greg Roman.
A familiar face is also among the new staffers set to join the Chargers. Los Angeles has hired former Pro Bowl center Nick Hardwick as an assistant O-line coach, Mike Garafolo of NFL Network reports. Hardwick spent his entire 11-year playing career with the (San Diego) Chargers, but this will be his first coaching position at the NFL level. He and Mike Devlin will aim to oversee improvement up front as part of the development of the team’s offense as a whole.
Chris O’Leary is also joining the Bolts as safeties coach, per the team’s announcement. O’Leary previously spent the past three years in the same role with Notre Dame, and he will join a number of staffers (including Harbaugh himself) in making the jump from the college to the pro level. This post will be O’Leary’s first in the NFL.
Other notable names on the new staff include Rick Minter, who has been brought on under the title of senior defensive analyst. He is the father of Jesse Minter, who as expected followed Harbaugh from Michigan to Los Angeles to become the team’s defensive coordinator. Dylan Roney – who has held a number of positions in the college ranks since graduating from Ferris State in 2018 – has been hired as a defensive assistant.
Those two will be joined on the defensive staff by Steve Clinkscale. The latter will take on the title of defensive backs coach. Clinkscale, 46, served under Harbaugh on Michigan’s staff beginning in 2021. He coached the Wolverines’ defensive backs during that time, while also working as co-defensive coordinator for the past two years. While a number of changes have been confirmed, continuity on special teams will be present on the 2024 staff. ST coordinator Ryan Ficken will remain in place, and the same will be the case for assistant Chris Gould. The latter (brother of veteran kicker Robbie Gould) has been in Los Angeles since 2022.
