Brandon is hiring the next coach not Buddy. Whaley's involvement in the coaching search would lead me to belive that Buddy gets some nebulous, Modrak-like role once the draft is over.
No established HC would want to come to Buffalo if Buddy was truly "in charge". I think Russ knows that.
If some old Pittsburgh guy gets the job (Wiz, Horton, Arians, or even Grimm) that would signal that Whaley is going to move up the food chain fast.
