From ESPN:
Statement from Bills owner Terry Pegula on firing of GM Doug Whaley this morning: "After a thorough review of our football operations over the past several months, Kim and I informed Doug this morning that we will be moving in a new direction. We have enjoyed working with Doug. He is a good person and we want to thank him for his work and commitment to our football team. This was my decision. It was not an easy decision but I believe it's the right one for the future of the Buffalo Bills. Our search for a new general manager will begin immediately."
