Norv Turner coaching the Chargers

Getting rid of Marty Schottenheimer is looking more and more like a bad idea. The Chargers waited so long to do it that there were not too many experienced coaches left. So they hired Norv Turner, who does not have a good track record as a head coach, with an overall losing record. How is he going to do a better job? I don't see that happening. The guy who should have left was AJ Smith, the GM. At least there would have been some continuity with the coaching. I don't see the Chargers improving next year.
