Believe everyone agrees that the offense is not performing well in any phase. But you're ignoring context. Part of the reason the offense isn't scoring is because they don't have the ball. There is most definitely an issue with the defense consistently giving up long drives and not getting turnovers. This translates into fewer opportunities for the offense to score. Again, not trying to ignore problems with offense, but don't throw out statistics without also acknowledging the context. This team just doesn't play complimentary football, that's 100% on McVay to recognize and fix. He hasn't.
