Tarver served as the defensive coordinator for the Oakland Raiders from 2012-14. He helped oversee a unit that ranked 10th in the NFL in yards per carry allowed (4.05) over his three seasons.  In his first season as the Raiders defensive coordinator, Oakland’s defense improved from 29th overall in 2011 to 18th in 2012.

Prior to his time in Oakland, Tarver served as the co-defensive coordinator/inside linebackers coach at Stanford University in 2011. Under his guidance, the Cardinal defense ranked third in the nation in rushing yards allowed per game (84.4) and 11th in points allowed per game (16.41). Stanford finished the season with an 11-2 record, ranked seventh in the final Associated Press poll and competed in the Fiesta Bowl.

From 2001-10, Tarver was a member of the 49ers coaching staff. Over his decade-long tenure with the team, he spent time as an offensive quality control coach (2001-03), assistant running backs/offensive assistant (2004) and outside linebackers coach (2005-10).

In 2009, Tarver’s outside linebackers registered 15 takeaways, 17.5 sacks and nine forced fumbles, while leading a defense that ranked sixth in the NFL in rushing yards allowed per game (97.0). The 49ers defense also ranked tied for third in the NFL in sacks (44), tied for first in forced fumbles (21) and fourth in points allowed per game (17.6). San Francisco’s run defense experienced similar success in 2010, ranking sixth in rushing yards allowed per game for the second consecutive season (96.7).

Before joining the 49ers staff, Tarver spent three years as a graduate assistant with UCLA from 1998-00. He worked primarily with defensive backs, while also assisting with special teams. During his tenure with the Bruins, he helped produce several future NFL players, including CBs Ricky Manning and Jason Bell, and S Marques Anderson.

Tarver played football at West Valley Junior College in Saratoga from 1994-95. He then spent the following two seasons as an assistant coach on the West Valley staff, supporting linebackers, defensive backs and special teams.

A Northern California native, Tarver and his wife, Katie, have two sons: Merrick and Keegan. He earned his bachelor’s degree in chemistry in 1997 from Santa Clara University and later earned his master’s degree in biochemistry and molecular biology from UCLA, where he received the departmental prize for distinguished teaching in 1998 and 2000.
