Mike Vrabel turned down Chip Kelly, and Kelly turned down Eric Mangini.
Ten days after Kelly was hired as 49ers head coach, the assistant-coaching position seen as the major piece to his staff remains vacant. The 49ers have most positions filled on their staff, but defensive coordinator remains vacant.
Vrabel decided to remain as linebackers coach of the Houston Texans, while Mangini interviewed to retain the position he held last year on Jim Tomsula’s staff before he was reportedly removed from consideration on Friday.
Jason Tarver remains as the top in-house candidate to run the 49ers’ defense. Tarver served three seasons as the Raiders’ defensive coordinator under Dennis Allen. In his first season, the Raiders improved from 29th overall before he arrived to No. 18 in the NFL in 2012. The 49ers ranked 21st in his final season before Tomsula hired him as senior defensive assistant/linebackers.
Others who have been identified as potential candidates are Don Martindale, the Baltimore Ravens’ inside llinebackers coach of the past four seasons, and former Cleveland Browns defensive coordinator Jim O'Neil, whom Bleacher Report on Sunday reported someone who has drawn Kelly’s interest.
The 49ers have not made any official announcements of additions to Kelly’s coaching staff because the team says no contracts have been officially signed. On Friday, the 49ers hired former Detroit running backs coach/run-game coordinator Curtis Modkins as offensive coordinator, according to ESPN. The team also expected to hire former Chicago assistant special teams coach Derius Swinton to become special-teams coordinator, reported the Sacramento Bee.
