San Diego free agency primer
Posted by ESPN.com's Bill Williamson
Salary cap situation: The Chargers will be in the $15-20 million range. They will be able to do a few things if they decide to.
Needs: Linebacker, defensive tackle, safety, guard.
How active will they be?: The Chargers usually rely on the draft and keeping their own players. They are concentrating on redoing the deal of running back LaDainian Tomlinson and signing stars such as quarterback Philip Rivers and tight end Antonio Gates this offseason. There may be some additions but, as always, the Chargers will be selective.
