We had this problem last year, and PC took all the blame for lacking any new ideas. Now, the board is full of comments that Kubiak is predictable and can’t adjust because we can’t protect the QB or block the run. Scheme gets too much credit/blame.
That said, the last four games help to show (again) that a team can only establish an identity when things are working. Kubiak was the savior in weeks one and two because we could run the ball at will against two bad teams, now he’s allegedly out of ideas. Establishing a run first identity is practically impossible when your lead back is averaging 3.3 a carry over the last four games. You practically have to pass the ball, especially when you can’t stop anyone, but we have no dominant receiving threats to lean on (and we’re currently depending on a 5th round QB as well).
