This Is Progress for the Bills?

I have to admit that I am not entirely sold on the appointment/promotion of Turk Schonert by the Buffalo Bills to offensive coordinator from quarterback coach.
Yes, Schonert, and even the prime minister of Turkmenistan, would no doubt be an improvement over Steve Fairchild, who, for some reason, was hired by his alma mater, Colorado State, to be their head coach.
But Schonert was the quarterback coach during a pretty bad time in the Bills' history for quarterbacks, and the lack of progress of former starting quarterback J.P. Losman, and meager progress of rookie quarterback Trent Edwards, is not a good sign on the question of Schonert's qualifications. Shouldn't Schonert have at least been able to help Edwards, a rookie needing coaching and, like Schoenrt, a Stanford graduate, show some improvement by the end of the season?
I hope my worries are overdone, but I don't have a real good feeling on this hiring, which no doubt was aided by the Bills' and owner Ralph Wilson's wish to stay in house.
