The 49ers this evening announced the hiring of three assistant coaches. Two we already knew about. Vic Fangio, 52, will replace Greg Manusky as defensive coordinator. Greg Roman, 38, is the new offensive coordinator.
The third hire is somewhat of a surprise. The team announced that Tim Drevno will take over as offensive line coach. Mike Solari, who ran the offensive line in 2010, is expected back next season and he and Drevno, 41, will coach the unit together. The 49ers had two offensive line coaches in 2008 when both George Warhop and Chris Foerster were on the staff together. When head coach Mike Nolan was dismissed midway through the season, Warhop was fired along with him.
This past season, Ray Brown served as Solari's assistant offensive line coach. There is no word yet on where Brown will end up.
Drevno is a long-time associate of Harbaugh's having served under him first at the University of San Diego, where he was offensive coordinator and offensive line coach, and later at Stanford. Drevno coached the Cardinal's offensive line the last two seasons, a span in which the unit allowed just 13 sacks. Stanford ranked second in the nation in sacks allowed in 2009 (7) and in 2010 (6).
Drevno also has served as offensive line coach at Idaho for three seasons (2000-02) as San Jose State's offensive line coach (1999), UNLV (running backs - 1998) and at Montana State (tight ends - 1993-95; running backs 1996-97).
"I am very excited that these three men are now part of the 49ers coaching staff," Harbaugh said in a statement. "They bring a wealth of knowledge and a level of professionalism that I am certain will transfer positively to our team. Vic has 24 NFL seasons under his belt and Greg has 13, so they know firsthand what it takes to win at this level."
