The primary problem of the 2018 Cal offense was an inability to make downfield plays in the passing game without turning the ball over at an unacceptable rate.
There were other issues - the aforementioned lack of running game explosiveness being the most obvious - but many of Cal’s other problems stemmed from an inability to pass downfield, which had knock on effects on the rest of the offense.
OK, so now that we’ve identified what worked and what didn’t, we can move on to the next question: What will it take to fix these problems, and can the current coaching staff and roster fix them?
