Backup: Charlie Whitehurst

Best-case scenario: The Chargers get a healthy Antonio Gates, and their wide receivers Malcolm Floyd and Vincent Brown step up. Also, it wouldn't hurt if Ryan Mathews figured out how to get healthy and stopped fumbling the rock. At best the Chargers complete their first winning season since 2009 and secure a Wildcard berth.
Worst-case scenario: Philip Rivers fails to deliver and continues his rapid fall from the second-tier quarterbacks club to the mediocre. Norv Turner gets reconstructive surgery on his scrotum neck and laughs at Mike McCoy for leaving Denver to take such a shitty gig in SD.
