A breakdown of the 49ers 2015 coaching staff in photos.
With Monday's announcement, the San Francisco 49ers have hired eight assistants who have at least 10 years of NFL coaching experience.
Experience means track record, and each of these eight men have one.
Chris Foerster is no different.
Look at the 49ers new (and old) offensive line coach -- he also coached here from 2008 to '09 -- and you'll find a man who has presided over dominant running games.
With San Francisco over those two seasons last decade, for example, Frank Gore ran for 1,036 yards and six touchdowns in '08 before racking up 1,120 yards and a career-high 10 scores in '09.
Foerster, who has run multiple schemes in his 22 NFL seasons, took this success to Washington. Under his watch, the NFC East member's offense live ranked first in rushing yards per game in 2012 (169.3) and fifth in '13 (135.2) before the offense as a whole fell on hard times in '14.
Presumably, Foerster is back in Santa Clara to both help the 49ers running game return to its usual heights while also cleaning up the unit's pass-protection.
The San Francisco 49ers new offensive line coach has worked in the NFL every season since 1993.
He'll be surrounded by a few familiar faces from his first go-around with the team. The offensive staff is led by coordinator Geep Chryst and comprises assistant offensive line coach Eric Wolford, who has never coached in the NFL but did spend the past four years as Youngstown State's head coach.
Foerster worked for former San Francisco head coaches Mike Nolan and Mike Singletary in 2008 and 2009. When he left in '10 to join Washington, he was replaced by Mike Solari, who held the position here through the 2014 season.
Foerster has also coached with the Minnesota Vikings (1992), the Tampa Bay Buccaneers (1996-2001), the Indianapolis Colts (2002-03), the Miami Dolphins (2004) and the Baltimore Ravens (2005-07).
Foerster was a Colorado State graduate assistant in 1982 after he was the school's center for four years starting in '79.
Foerster will have the opportunity to coach 49ers Pro Bowl left tackle Joe Staley, but he is no stranger to high-profile pupils, having coached Hall of Fame inductees Jonathan Ogden (Ravens left tackle) and Randall McDaniel (Vikings guard).
