Chargers agree to deals with Brandon Mebane, Dwight Lowery

SAN DIEGO -- The Chargers have been searching for a true nose tackle since Jamal Williams last played for team in 2009.

And the Chargers appear to have found their man in former Seattle Seahawks defensive tackle Brandon Mebane, signing him to a three-year deal at the start of free agency on Wednesday.

The Chargers also agreed to a three-year deal with former Indianapolis Colts safety Dwight Lowery, tendered safety Jahleel Addae (second round, $2. 553 million), along with tendering exclusive rights free agents receiver Dontrelle Inman and offensive lineman Kenny Wiggins.

The Chargers also added to their offense on Wednesday with the signing of wide receiver Travis Benjamin and re-signing of tight end Antonio Gates.

A Los Angeles native, Mebane was one of the main reasons Seattle has had one of the best run defenses in the NFL over the past five seasons.

And that's an area the Chargers needed to improve. San Diego gave up 4.8 yards per carry last season, third-worst in the NFL. The Chargers also allowed a league-worst 21 runs of 20-plus yards.

Mebane's impact shows up more on film than it does on the stat sheet. Coaches and teammates raved about Mebane's performance against the run last year, as the Seahawks held opponents to 3.6 yards per carry (third best in the NFL).

Originally a third-round pick in 2007, Mebane (6-foot-1, 311 pounds) spent nine seasons with the Seahawks. He is a two-down nose tackle who played 49.1 percent of the team's snaps last year.

Mebane, 31, won't generate much of a pass rush, but he can still hold up at the point of attack in the run game.

Lowery was signed by the Colts later in the free-agency period in 2015 and was an immediate starter at safety.

Lowery, 30, started all 16 games last season, registering 76 tackles, four interceptions and eight passes defended.

His best game was in Week 3, when he intercepted Tennessee rookie quarterback Marcus Mariota twice, including one that he returned for a touchdown, in the Colts' victory.
