The Chargers and recovering their Season

The Chargers had a very rough start to their season this year and the reason is that they had some pivotal changes to their franchise. Not in the team lineup, but the coaching. Marty Schottenheimer lead the team to a great record as well as the playoffs. The Chargers were a real threat and potential competitor for the Superbowl. Why did they fire him and hire Norv Turner? The Chargers were a real threat and this was minimized by getting rid of a good coach that had them on the brink of a title. If the Chargers were a disaster than it would be understandable, but they were not.
