Can't say I'm surprised, I thought Doug did as well as he could given the players he had to work with, but you can't expect to keep your job after a 4 win season. The last 2 times the Eagles had a 4 or less win season the coach was fired.
Also seems even if they were willing to cut him some slack because of the circumstances this year the rumors are he was not happy with being told to do certain things, it sounds like management was interfering with what he wanted to do.
