Los Angeles Chargers Announce Coaching Staff Additions

Feb 14, 2024 at 11:00 AM

The Los Angeles Chargers today announced multiple additions to Head
Coach Jim Harbaugh's staff for the 2024 season. Along with the
additions, which are listed below, Special Teams Coordinator Ryan
Ficken, Assistant Special Teams Coach Chris Gould and Defensive Quality
Control Coach Robert Muschamp will continue in their roles on the
coaching staff.

Andy Bischoff brings extensive coaching experience to the Chargers as
run game coordinator/tight ends coach. He coached the tight ends for the
New York Giants from 2022-23 and Houston Texans in 2021, helping the
Giants in 2022 reach their first postseason appearance since 2016. He
spent six seasons (2015-20) with Baltimore in a variety of roles on
offense, working primarily with the tight ends over his final four years
with the Ravens. Bischoff was the assistant tight ends coach from
2019-20, helping Mark Andrews lead all NFL tight ends with 17 touchdown
catches over that span.

Prior to his time in Baltimore, Bischoff spent two seasons with the
Chicago Bears as tight ends coach/staff coordinator (2013-14). He worked
in the Canadian Football League for the Montreal Alouettes as a running
backs/offensive quality control coach from 2008-09, adding special teams
responsibilities to those duties from 2010-12. Bischoff began his
coaching career at Cretin-Derham Hall High, coaching there from
1993-2007. He coached 18 offensive linemen and three tight ends to earn
Division I scholarships, including former NFL players Matt Birk, Ryan
Harris and Michael Floyd.

NaVorro Bowman, a four-time Associated Press first-team All-Pro at
linebacker with over 100 career games played, makes his NFL coaching
debut with the Bolts as linebackers coach. He is reunited with Head
Coach Jim Harbaugh, who coached him for four seasons with the San
Francisco 49ers to earn three of his AP first-team All-Pro selections
and a pair of Pro Bowl nods. Bowman was one of the NFL's most dominant
defensive players during his career, totaling over 800 tackles, 16.5
sacks and five interceptions in the regular and postseason combined. He
was a third-round selection of the 49ers in the 2010 NFL Draft (91st
overall) out of Penn State, playing seven-plus seasons with San
Francisco before finishing his career with Oakland. Following his
retirement in 2018, Bowman got his start coaching last season at the
University of Maryland as a defensive analyst.

A 23-year coaching veteran at the collegiate level, Steve Clinkscale
comes to Los Angeles to coach defensive backs after a three-season
tenure as secondary coach at the University of Michigan (2021-23). He
added co-defensive coordinator responsibilities last season, helping
lead the top-ranked defense in college football, allowing just 247.0
total net yards per game as the Wolverines posted a 15-0 record and
finished by winning the College Football Playoff National Championship.
Prior to his time at Michigan, Clinkscale coached defensive backs at the
University of Kentucky for five seasons (2016-20) and at the University
of Cincinnati for three seasons (2013-15), adding defensive coordinator
responsibilities for the Bearcats his final season. He got his start in
coaching as defensive backs coach at his alma mater, Ashland University,
from 2001-07 before coaching defensive backs at Western Carolina in
2008. Clinkscale then spent three seasons at Toledo (2009-11) as
cornerbacks coach/special teams coordinator before coaching cornerbacks
at Illinois in 2012.

Shane Day returns to the Chargers as quarterbacks coach after spending
the 2023 season with the Houston Texans as a senior offensive assistant.
He helped quarterback C.J. Stroud win Offensive Rookie of the Year
honors from The Associated Press after eclipsing 4,000 passing yards and
totaling 23 touchdown passes to lead the Texans to an AFC South title
and a playoff victory. Day spent two seasons with the Bolts as passing
game coordinator/quarterbacks coach (2021-22), coaching quarterback
Justin Herbert in 2021 to a Pro Bowl selection after setting
single-season franchise records in completions (443), passing yards
(5,014), passing touchdowns (38) and games with 300-plus passing yards
(nine).

Before his time with the Bolts, Day coached quarterbacks for the San
Francisco 49ers from 2019-20. He tutored quarterback Jimmy Garoppolo in
2019 to lead the 49ers to Super Bowl LIV and be named NFL Comeback
Player of the Year by Sporting News. Day began his NFL coaching career
with San Francisco as an offensive quality control coach from 2007-09
before coaching quarterbacks for Chicago (2010-11). After a two-season
tenure coaching quarterbacks at the University of Connecticut (2012-13),
Day returned to the NFL as an assistant offensive line coach for
Washington from 2014-15 and then coaching tight ends for Miami from 2016-18.

Mike Devlin brings 21 years of NFL coaching experience to the Bolts as
offensive line coach, a position he's held with the New York Jets and
Houston Texans for a total of eight seasons. He most recently spent two
years (2022-23) as the assistant offensive line coach for the Baltimore
Ravens, helping guard Kevin Zeitler and center Tyler Linderbaum to Pro
Bowl nods this past season. In 2022, Devlin coached Linderbaum to start
all 17 regular-season games and be recognized as an All-Rookie selection
from the Professional Football Writers Association.

Devlin was the offensive line coach for the Houston Texans (2015-20) and
New York Jets (2013-14) before his time in Baltimore. He coached Nick
Mangold (two), Laremy Tunsil (two) and Duane Brown (one) to earn Pro
Bowl selections. Devlin coached tight ends for the Jets from 2006-12,
his first appointment as an NFL position coach, after coaching the
offensive line at the University of Toledo for two years (2004-05). The
1992 Big Ten Offensive Lineman of the Year at the University of Iowa,
Devlin was a fifth-round selection by the Buffalo Bills, playing there
from 1993-95 before playing four seasons with the Arizona Cardinals
(1996-99). Following his pro career, Devlin got his start at coaching
with the Cardinals as the assistant offensive line coach from 2000-03.

A 27-year coaching veteran, Mike Elston comes to Los Angeles to coach
the defensive line after holding the same position while also working as
a recruiting coordinator the last two seasons at the University of
Michigan, his alma mater. He coached a Wolverines defensive line in 2023
that was part of the top-ranked defense in the country, allowing just 17
touchdowns on the season and averaging 247.0 yards allowed and 10.4
points allowed per game. Elston played outside linebacker at Michigan
from 1993-96, before beginning his coaching career with the Wolverines,
working for the program from 1997-2000 in various capacities. He was a
student assistant coach in 1997 for the program's National Championship
campaign. The next year, he was a video intern before working as a
graduate assistant coach from 1999-2000, working with the outside
linebackers.

Elston then coached defensive ends during the 2001 season at Eastern
Michigan before switching to recruiting coordinator/defensive line coach
(2002-03). He went to Central Michigan to coach the defensive line in
2004, adding co-defensive coordinator duties in 2005 before
transitioning to special teams coordinator/linebackers coach in 2006 for
the Chippewas. Elston moved on to Cincinnati, coordinating the special
teams from 2007-09 while also coaching tight ends for his first two
seasons and defensive line for his third season with the Bearcats. In
his final stop before his return to Michigan, Elston coached at the
University of Notre Dame from 2010-21, tutoring the defensive line nine
seasons (2010-14, '17-21) and the linebackers from 2015-16. He held
numerous additional roles for the Fighting Irish, including special
teams coordinator (2010-11), recruiting coordinator (2015-17, '21),
associate head coach (2018-20) and run game coordinator (2021).

With 17 years of NFL coaching experience, Sanjay Lal joins Los Angeles
as the team's wide receivers coach after working as the passing game
coordinator/wide receivers coach for the Seattle Seahawks from 2022-23.
He coached wide receiver DK Metcalf to Pro Bowl selection after a
1,000-yard season and eight touchdowns in 2023. Lal coordinated a
passing attack in 2022 that featured AP Comeback Player of the Year Geno
Smith to register a 100.9 passer rating by throwing 30 touchdowns and
recording 4,282 passing yards, while both Metcalf and wide receiver
