SAN DIEGO (AP) -- The Chargers defense couldn't get off the field last season.
San Diego was last in the NFL at third down efficiency, a major reason the Chargers sat out the playoffs for the second straight year.
Cornerback Quentin Jammer says: "You can't win football games by being last on third downs."
Defensive coordinator Greg Manusky lost his job after the season. Longtime linebackers coach John Pagano took charge of the defense and the front office drafted defensive players with its first three selections. San Diego also signed two NFL veterans to start on defense.
