The San Diego Chargers backfield could look significantly different next season, since Ryan Mathews can leave the team during the offseason as an unrestricted free agent. They also can get out of Donald Brown's contract, if they choose too, since he has no remaining guaranteed money. Branden Oliver will be back on the cheap.

Could the Chargers set their sights high on a potential free-agent stud to top off their RB depth chart?
