The Bills seem to have gone out of their way to distance themselves from Tyrod. I also believe that our new OC isn't that impressed with Tyrod in his new scheme.
Peterman is a coach's player. He'll do what you ask of him. I think Tyrod is on a short leash and the coaching staff isn't under any threat to "win now" based on the front office clean out.
I think you'll see Peterman on the field this year.
