Four years is more than a lifetime in this business and he has never produced anything resembling a top unit or a dominant unit in any of those four years. Rex Ryan did it with essentially the same group of guys that he inherited in less than six months. Immediate, significant and measurable difference in every performance category because a superior coach was brought in to do the job.
Immediate, significant and measurable differences. Three things which in four years we have not seen from your boy.
Every year there is an excuse for why it is not the fault of the guy in charge. One year it is the offensive line, then it is lack of talent at the running back position, then it is the noodle-armed QB who defenses are not scared to stack the box against, then it is the the new young QB (Clemens), then it is the new OLD QB who is learning a different system for the first time in 17 years, then it is the lack of a true number one receiver, then it is the next new young QB who is being thrown into the starting job as a rookie. Now it is losing a really good change of pace back who had been deballed and turned into so-so sometime starter by this lame OC.
When do the excuses end? Ever???
Every team has injuries and changes in personnel every single year. Duh.... Every team. Some coordinators manage to adapt and be successful with the talent they have on hand and some are below average every year. Never mind though, we could be doing this for another decade and I am sure his army of apologists will be dreaming up reasons why it is not Brian Shottenheimer's fault no matter what.
Whose fault is it next year? Sophomore QB?
