After the 49ers' "mutual parting" with head coach Jim Harbaugh, general manager Trent Baalke informed the vast majority of the staff members that their services would no longer be needed under new coach Jim Tomsula.

Yet, with the new staff largely assembled, the top three positions are held by holdovers from Harbaugh's staff.

Tomsula makes the dramatic leap from defensive line coach over former defensive coordinator Vic Fangio for the head-coaching position. Geep Chryst, whose main job was to help develop Colin Kaepernick as quarterbacks coach, reportedly gets the call as offensive coordinator -- the most-important job on the staff. And ex-tight ends coach Eric Mangini switches back to the other side of the ball as defensive coordinator.

49ERS COACHING STAFF
Jim Tomsula, head coach – He did not provide many clues about his vision for the team at his introductory press conference. He'll likely delegate complete autonomy to his coordinators after spending the past eight seasons as defensive line coach.

Geep Chryst, offensive coordinator – He is a holdover from the previous staff, on which he served as quarterbacks coach. The 49ers went strong after Adam Gase, but he opted to follow his former boss, John Fox, to the Chicago Bears. Rob Chudzinski, Mike Shanahan, Kyle Shanahan, Bob Bicknell and Lane Kiffin were also mentioned as coaches in whom the 49ers had interest. Chryst will reportedly receive the promotion to the top assistant.

Eric Mangini, defensive coordinator – The 49ers are expected to keep the 3-4 scheme that was implemented under former coordinator Vic Fangio. He spent just one season (2005) as New England Patriots defensive coordinator before head-coaching gigs with the New York Jets and Cleveland Browns.

Steve Logan, quarterbacks – Logan will work closely with Colin Kaepernick, whom he described Wednesday as “my kind of guy – mobile, accurate and smart." Logan was an assistant, along with Tomsula for two seasons in NFL Europe, before serving as offensive coordinator when Tomsula was head coach of the Rhein Fire in 2006.

Thomas McGaughey, special teams coordinator – The former NFL Europe colleague of Tomsula spent one season running the New York Jets’ special teams under Rex Ryan.

Tom Rathman, running backs – The former 49ers fullback will return for his 13th season on the team’s coaching staff. His first stint ran from 1997 to 2002. In his return, he’s been on the staff since 2009.

Tony Sparano, tight ends – He last coached tight ends with the Dallas Cowboys in 2003 and ’04. After a one-year stint in 2012 as New York Jets offensive coordinator, Sparano coached the Raiders offensive line. He was the Raiders interim head coach and finished as the runner-up to Jack Del Rio for the permanent job.

Chris Foerster, offensive line – He was let go as 49ers line coach in 2010 in favor of Mike Solari. Now, he replaces Solari after spending the past five seasons with Washington.

Eric Wolford, assistant offensive line – The former Youngstown State head coach was briefly on the Oklahoma State staff before getting his shot to coach in the NFL.

Jason Tarver, senior defensive assistant/linebackers – The former Raiders defensive coordinator will have some play-calling responsibility. He will likely be entrusted to develop some blitz schemes.

Ronald Curry, TBA – The former Raiders wide receivers spent two seasons with the 49ers as an offensive assistant. The 49ers denied the Buffalo Bills permission to hire Curry as their wide receivers coach. Whether he gets that title with the 49ers or not, he’ll work closely with that position group.

Aubrayo Franklin, TBA -- The former 49ers nose tackle will fill an entry-level defensive coaching position.

Ejiro Evero, TBA – After four seasons with the 49ers as defensive assistant, the former UC Davis safety could have an expanded role as an assistant defensive backs coach.

Mick Lombardi, TBA – He came to the 49ers in 2013 as “assistant to the head coach.” Last season, he moved into a coaching role as “offensive assistant.”
