Chargers released CB Derek Cox. Cox inked a four-year, $20 million contract on the second day of free agency last year and received $10.25 million guaranteed for one season of utterly mediocre play. The Chargers save $4.25 million in cash but are eating $3.9 million in dead money against the cap. The move clears just $1.65 million in cap space. Cox was benched multiple times last season. He was deemed expendable for a team that really needs corner help. Cox is still just 27 years old.
