Alan Williams
Defensive Backs/Safeties


With more than 10 years of experience coaching NFL defensive backs, Alan Williams joins the Lions staff in 2014 as the team’s defensive backs/safeties coach after serving as the Minnesota Vikings defensive coordinator for the last two seasons (2012-13). He enters his 14th season coaching in the NFL, with previous stops with the Indianapolis Colts (2002-11) and Tampa Bay Buccaneers (2001). In 2006, he mentored the Colts’ defensive backs en route to the team’s 29-17 win over the Chicago Bears in Super Bowl XLI.


During Williams’ tenure as defensive coordinator in Minnesota (2012-13), the Vikings were tied for seventh in sacks with 85 and ninth in tackles for loss with 91. In 2013, the Vikings defense overcame a variety of injuries as three players in the defensive backfield, S Andrew Sendejo, CB Marcus Sherels and CB Shaun Prater, logged their first career interceptions under Williams’ watch. Veteran DE Jared Allen led the team in sacks with 11.5, his seventh straight season with 10+ sacks, as fellow DE Brian Robison recorded a career-best nine.

In his first season with the Vikings, he oversaw a unit that drastically improved in overall defense as the team won its final four games to earn an NFC Wild Card berth after missing the postseason the previous two seasons. That season, Allen and LB Chad Greenway were selected to their fifth- and second-consecutive Pro Bowls, respectively, as the defense improved to No.16 in total defense after their No. 21 finish in 2011.

Williams spent a decade coaching the Indianapolis Colts secondary where he worked with some of the League’s most elite defensive backfield talent, including S Antoine Bethea and S Bob Sanders. From 2002-11, the Colts ranked in the Top-6 in the NFL in passing defense five times and finished out of the Top-15 only once. Williams guided Bethea (2007, 2009) and Sanders (2005, 2007) to two Pro Bowl seasons each. Sanders was named AP Defensive Player of the Year in 2007, the first Colts player to ever receive the honor.

From 2002-10, the Colts earned nine-consecutive playoff berths, during which the defense recorded 18 interceptions in the playoffs, including seven during the team’s playoff-run to their Super Bowl XLI win over Chicago in 2006. Williams’ secondary also helped the Colts defense in 2008 set an NFL record for fewest passing touchdowns allowed with six, the lowest number ever surrendered in a 16-game season.

Williams began his NFL coaching career with the Tampa Bay Buccaneers in 2001 as a defensive assistant under former head coach Tony Dungy, where he worked with All-Pro players in the likes of John Lynch and Ronde Barber. That season, Williams coached alongside current Cowboys Assistant Head Coach of Defense Monte Kiffin and Steelers Head Coach Mike Tomlin as the Bucs finished 9-7 and earned an NFC Wild Card berth.

A former standout running back at William & Mary from 1988-91, Williams later returned to his alma mater where he coached the running backs and defensive backs for five seasons (1996-2000). His first coaching stint was as an assistant head coach at Norview (Va.) High School where he kindled his craft for working with running backs and defensive backs from 1992-95.

Williams was born November 4, 1969. He is a native of Norfolk, Va. and he and his wife, Lisa, have three children – Christian, Solomon and Nathan.
