re: Shouldn't Salary Scale with Results?

Could we not pay a less high profile offensive coordinator to do the job that's currently being done? I'm not saying fire Cameron or cut his salary - that's not happening and that's not how it works. But it's a serious question to ask if we're going to win the philosophy of Miles, which is defensible, then why spend so much on an OC when it's not necessary and it doesn't change the results on the field much?
