Chargers: One big question

Did the Chargers do enough on defense?

If the San Diego Chargers are going to end a two-year playoff drought and coach Norv Turner and general manager A.J. Smith are going to save their jobs, the defense must make strides.

The unit was the worst in the NFL on third down last season, and it lacked fire.

Improving the defense was one of the primary goals in the 2012 offseason. Defensive coordinator Greg Manusky, who some in the organization believe was a major reason for the unit's lack of success, was fired, and linebackers coach John Pagano replaced him. Pagano reminds some of former successful San Diego defensive coordinator Wade Phillips because of his approach.

The team signed underrated former Baltimore linebacker Jarret Johnson in free agency and concentrated on defense in the draft.

San Diego drafted South Carolina pass-rusher Melvin Ingram, Connecticut defensive tackle Kendall Reyes and LSU safety Brandon Taylor in the first three rounds. All three players are expected to contribute right away.

Ingram is highly regarded and has a chance to make an instant impact as a pass-rusher, which the Charges badly need. If these players develop quickly and Ingram is as polished as expected, the Chargers should be much more effective defensively.
