I'm not seeing the overall dysfunction and incompetence on offense that others are. They've moved the ball well between the 20s. While it hasn't always been sharp, it has struck me as relatively functional, especially for a first-year, first-time OC.
The real issue lies in red-area execution and situational football (the two of which are not mutually exclusive). They're not scoring enough points. This comes down to coaching and QB play, and is absolutely where the impact of Patricia and Judge is being felt.
Judge, in particular, has no business coaching the QBs. None, at all. Patricia I think is smart and experienced enough to manage a functional offense but he lacks the polish, nuance, and attention to detail of a long-time OC, which really comes down to accrued experience coaching offense, which Patricia doesn't have under his belt. This manifests as poor situational timing/execution, particularly in the red-area.
