Key unrestricted free agents: Running back/returner Darren Sproles, guard Mike Goff and defensive lineman Igor Oklshanky. Sproles will likely be the team's top target. While he is too small to be a primary tailback, the Chargers need to keep him because he is so versatile.
Dream free agent match: Baltimore linebacker Bart Scott. He is an underrated player who could fit in well with the Chargers who could use another playmaker.
