Why do you think he is "saving face". The guy turn down the DC job at Florida to come to Buffalo. He might actually be well repsected by people who know the game? Edwards was a first year DC and he had the worst front 7 in the NFL to work with. They sucked at stopping the run before he ever got there and on top of that they ask him to switch to a 3-4. Here are your linbebackers - Chris Ellis, Aaron Maybin, Poz, Ellison and Chris Kelsey .. Good Luck Mr. Edwards!! Oh, and your best player Aaron Schobel, he retired. But don't worry we will give you Dwan Edwards, Andra Davis, Troup and Carrington. woo hoo!!
Just maybe Edwards is a bright and talented guy that will learn from Wanstadt?
Look at the Pats*. They lost both coordinators and their GM and they replaced them from within. good organizations grow talent from within, that includes Players, coaches, scouts, and front office.
