Chargers: Backup QB plan

Assessing the San Diego Chargers' backup QB situation if Philip Rivers is injured and misses time.

The Chargers are taking a risk by going with Charlie Whitehurst as Rivers’ backup. Whitehurst spent four seasons with the Chargers and was traded to Seattle two years ago. The Seahawks had designs that Whitehurst (a preseason star in San Diego) could become solid starter. It never happened and he finished 1-3 as a starter in Seattle. When he became available this offseason, San Diego cut longtime backup Billy Volek in a salary-cap move and went with the younger Whitehurst, who is 29. He is comfortable in San Diego, and the Chargers like him. Still, I think Volek would have been a better option if Rivers was to go down.

Confidence rating (out of 100) if Rivers is out for an extended period: 15.
