While it may be a little bit of "all of the above," I think the biggest issue is that the playcalling has been predictable. Fitz is getting handoffs on a limited number of plays, and almost always on 1st down. Give him some space to run, and I think he's doing fine.
"Coach Mattison told me what the Ravens were about, what he thought," Beyer said. "He definitely encouraged me. I hold his opinion in high regard."
