Most of our current players were recruited to run a different offensive system. That's a really big part of it.
That said, I'd like to see Herman play to the strengths of the guys we have a little more. Arnaud is a much better passer out of the play action, and rolling to his right (just like Stanzi), but we don't do a lot of it. A-Rob is great in space, but we almost never throw him screens. We have an ex-QB @ WR in Reynolds, and not once have we attempted a reverse pass with him this year.
I feel every week like Herman leaves something on the table, but we shouldn't calling for his head until he fails with his own players.
Great post.
