SANTA CLARA -- General manager Trent Baalke was busy Wednesday evening, calling many of the 49ers assistant coaches to inform them that their services are no longer needed with the organization.
Running backs coach Tom Rathman will be given the opportunity to return. And offensive line coach Mike Solari told CSNBayArea.com he will have a meeting with Baalke – not new head coach Jim Tomsula – on Thursday morning.
The big addition to the coaching staff, of course, will be offensive coordinator to replace Greg Roman, who was hired in the same position this week on Rex Ryan’s staff with the Buffalo Bills.
Most of the 49ers' focus will be on assembling an offensive staff to get more production from quarterback Colin Kaepernick and a 49ers offense that last season ranked 20th in the NFL in total yards, 25th in points scored, and 28th in red-zone efficiency.
Although there is no indication which direction Baalke and Tomsula plan to go, here are four strong candidates:
Rob Chudzinski, 46, got a lot out of his talent in two-year stints as offensive coordinator with the Cleveland Browns (2007-08) and Carolina Panthers (2011-12). Chudzinski was hired by Indianapolis Colts coach Chuck Pagano as "special assistant" this season when he was fired after just one year as Browns head coach. Mike Singletary interviewed Chudzinski for the 49ers’ offensive coordinator position in 2009, but he is believed to be one of the many who turned down that opportunity. He was offensive coordinator on the University of Miami staff while Frank Gore was playing. UPDATE: Chudzinski is expected to be a person who is targeted for the job, according to sources.
Marc Trestman, 59, the recently fired Chicago Bears coach, is considered a top offensive coach and quarterback mentor. He has a cerebral approach to the game and could be a good fit for helping Kaepernick develop his mental game. He previous worked as 49ers offensive coordinator under George Seifert. His tenure ended with former owner Eddie DeBartolo grabbing the microphone during Seifert’s farewell press conference and stating bluntly, “He’s gone.” But a lot has happened since then. And it’s conceivable the 49ers could bring him back to run the offense.
Bill Callahan, 58, has been an NFL coach since 1995. He was Raiders offensive coordinator for four seasons before taking over as head coach. The Raiders went to the Super Bowl in his first season after taking over for Jon Gruden, but he was out after the next season. The past two seasons he has worked as Dallas Cowboys offensive coordinator, though coach Jason Garrett delegated his play-calling duties to Scott Linehan, the team’s passing game coordinator. He is not expected back with the Cowboys next season. UPDATE: The 49ers have not contacted Callahan, according to multiple sources.
Adam Gase, 36, interviewed for the 49ers’ head coaching job twice with Baalke. Since it’s Baalke who appears to be putting together the staff, and the 49ers had a strong idea where this thing was going, Baalke had to broach the subject with Gase if he would be interested in becoming Tomsula’s offensive coordinator. Gase is in limbo with the Denver Broncos after two seasons there as the offensive coordinator, and St. Louis and Atlanta have already reportedly shown interest in him for their offensive coordinator positions. Stranger things have happened. UPDATE: This is definitely not going to happen, according to multiple people close to the situation.
Insider Matt Maiocco will discuss the 49ers' options for their open offensive coordinator position on Yahoo! SportsTalk Live tonight at 5 , 7, and 11 p.m. on Comcast SportsNet Bay Area.
