If you listened to Bills games years ago, Van Miller would run through a whole series of 'thank you's at game end, acknowledging the crew up in the booth and technical staff. I seem to recall at least two spotters (Dr. Ed Gusevitch being one), who I would guess would pass along info to Miller. Is it possible that staff has been pared down over the years, leaving the play by play and colour announcers to figure out what's occurring on the field.
