The Detroit Lions continue to add coaches and they continue to have some level of NFL experience.

The Lions have hired Tony Oden to be the assistant secondary coach and Matt Raich to be the defensive quality control coach.

Oden has been a coach since 1996 -- almost all as a defensive coach in the secondary. He spent the past two seasons in Tampa Bay as the team’s defensive backs coach and worked with the secondary in New Orleans from 2006 to 2011. Before that, he spent two years in Houston as an assistant defensive backs coach.

He also has extensive college experience after graduating from Baldwin-Wallace in 1996. He started at Millersville University in Pennsylvania and then went to Boston College, Army, East Carolina and Eastern Michigan before heading to the NFL.

Oden worked with Darrelle Revis in Tampa Bay. With the Buccaneers, the team was in the top half of the league in interception percentage his two seasons there, but allowed the most passing yards per game in the league in 2012.

In 2011, when he was the New Orleans defensive backs coach, the team was 30th against the pass and the worst team in the league in interception percentage. The Saints did make the playoffs his final three years with the club and won a Super Bowl in 2009.

Raich worked with Teryl Austin and former Detroit coaching candidate Ken Whisenhunt in Arizona. He spent his final four seasons in Arizona as the team’s linebackers coach. He came with Whisenhunt to Arizona from Pittsburgh, where he was an offensive coach with the Steelers. He started in the scouting department with Pittsburgh.

He spent last season with Duquesne, coaching the linebackers. He played linebacker at Westminster College, in NAIA, from 1989 to 1992.
