The 49ers haven’t announced any additions to Jim Tomsula’s staff, but the team’s new coach appears to be zeroing in on some familiar faces.
One of them belongs to Eric Mangini, a 49ers assistant coach the past two seasons. According to a league source, Mangini is in the mix for the defensive coordinator job, which opened when the team parted ways with Vic Fangio last week.
Mangini also is being considered by the Raiders. Washington interviewed him for its defensive coordinator opening but hired former San Diego Chargers linebackers coach Joe Barry.
Fangio was hired Tuesday by the Chicago Bears, who also could pick up another former 49ers defensive assistant, Ed Donatell, in the coming days. The 49ers finished fifth or better in total defense since Fangio and Donatell arrived in 2011.

Mangini was the 49ers’ tight ends coach last season and was an offensive consultant with the 49ers the year before.
His background before 2013, however, has been on the defensive side of the ball, especially with defensive backs. Mangini, 44, was the Patriots’ secondary coach (2000-04) before being promoted to New England’s defensive coordinator in 2005.
He then was a head coach for five years, first with the New York Jets (2006-08) and then the Cleveland Browns (2009-10). He spent two years as a television analyst before joining Jim Harbaugh’s staff in 2013.
The 49ers already have interviewed former Raiders defensive coordinator Jason Tarver, although Tarver’s possible role on Tomsula’s staff is not known. Tarver coached outside linebackers with the 49ers for six seasons before becoming Stanford’s defensive coordinator in 2011. He joined the Raiders the following year.
The Raiders also are considering Mangini for their defensive coordinator opening. And they announced Tuesday they had added former 49ers special-teams coordinator Brad Seely to their staff.
Seely, 58, arrived with Harbaugh in 2011 and was given the additional title of assistant head coach.
The 49ers could replace Seely with former Jets special-teams coach Thomas McGaughey, 41, who worked alongside Tomsula with the Scottish Claymores of NFL Europe in 2002. Tomsula coached the defensive line and McGaughey worked with special teams and defensive backs.
Tomsula is believed to be looking at several former colleagues from his nine-year stint in the European league.
McGaughey was LSU’s special-teams coordinator (2011-13) and joined the Jets last season. New York fired Rex Ryan at the end of the season and hired Todd Bowles to replace him.
Before LSU, McGaughey was an assistant special-teams coach with the New York Giants and Denver Broncos.
Mangini did not make a mark as a tight ends coach. The 49ers’ offense was decidedly more wide-receiver heavy in 2014 than it had been in previous seasons. Vernon Davis, the team’s top tight end, had just 26 catches for 245 yards and two touchdowns. Vance McDonald, a second-round pick in 2013, had two catches for 30 yards and finished the season with a back injury.
The 49ers could tap Geep Chryst, their quarterbacks coach from 2011 to 2014, to coach the tight ends, something he has done in the past. Chryst, however, has drawn interest from both the Bears and the Raiders. His son, Keller, is a quarterback at Stanford, which may prompt Chryst to remain in the Bay Area.
