Wanny is not calling the plays on D, Edwards is. Wanny might help in the scheming during the week, but Edwards is the ultimate decision maker. Wanny will bring better "in game" decisions and find better ways to get after the QB. Our DB's cant cover all day while the QB is dancing and waiting in the pocket. They need a big change on D and the best time would be right now with two weeks of preparation and adjusting. It cant be much worse could it?
