The fact is that Fisher and Schotty are responsible for the offense. I don't care if the offense is plodding and unproductive because of the players or the game plan. These are their players, brought here by them and Snead. They're the ones responsible. If you were a project manager in your 3rd year, and after being given everything you asked for still blamed your lack of success on your team, would that fly? I don't think it would. Of course not everything going on is his fault. But who are you going to hold accountable for a department's poor performance if not the dept head? I'm not trying to say he should be fired or anything, I'm just trying to point out that the criticism isn't sometimes fair, it isn't unfair either. He has called some good games, and he also has been guilty of calling some truly awful ones.
In some ways I think it would be a cop out to blame the players. Again, it's year 3, after some of the most favorable drafting conditions in our history. Saying the players aren't good enough may be true, but that comes back to them. Saying the game plan can't be called because of execution may be true, but whose fault is that if not the coaches? Walton rightly was fired for his bad game calling and poor execution by players, and his unit outperformed Schotty's.
I guess my long winded point is that holding the OC accountable for the YEAR TO YEAR state of the offense is not unreasonable.
