I'm a die-hard Chargers fan. Philip Rivers is not the problem.
With the talent they have, a 9-7 record is unacceptable. AJ Smith, the GM, makes poor personnel decisions. He should have swallowed his pride and paid Marcus McNeill and Vincent Jackson instead of forcing them to hold out for most of the season.
Norv Turner is a mediocre coach at best and isn't authoritative enough for a roster loaded with talented players. Smith and Turner need to go if the Chargers want real success.
