Well - this proves that this season is toast.
OTOH, as I linked to the other day, Roman's offenses in SF led or tied for the lead in delay of game penalties during his tenure there. He's just far too slow. And he doesn't seem to allow his QBs to audible, nor does he (in my opinion) use enough pre-snap motion to help his QB identify the defense and dictate favorable matchups in the passing game.
That said, he's a hell of a running game coordinator. He'll get a new gig shortly. The stink of this will remain at OBD. Roman will be fine. Everyone else around the league understands that the Bills' organization is a dysfunctional joke where it is impossible to succeed.
