Notes:
This is not an attempt to prove causality or correlations between who was coaching Cal’s defense and its performance. Instead, it’s simply data. And with all statistics, you have to view them as more directional than empirical. For football this is especially the case - for example, a good pass coverage will create sacks and a poor pass rush will result in a disappointing pass efficiency defense.
Many factors beyond coaching impact performance and statistical outcomes including but not limited to offensive performance, departing talent, depth and experience as well as injuries. As with any coaching staff, there are often multiple chefs in how a position is taught, coached up, and utilized schematically so viewing the positional coach as the sole responsible leader is not a holistic truth.
That doesn’t mean that trend lines and drop-offs aren’t impacted to a meaningful degree by assistant coaching. In the arms race of college football, the one that in our view has the greatest impact on a team's performance is the quality of its coaching staff. It impacts recruiting, player development, and in-game decision-making. At the end of the day, the entire staff is responsible for all factors of the success of the program.
- It’s interesting to note that the staff had changed every season until the past two years, by far the worst defensive performance under Justin Wilcox
- Jerry Azzinaro left to become UCLA's Defensive Coordinator and Tony Tuioti stepped in as the DL coach and had success, Tony’s currently the very successful DL coach for the Oregon Ducks. Azzinaro struggled with the Bruins and has since departed.
- Gerald Alexander left to join the NFL as the Miami Dolphins Defensive Backs coach and currently coaches the secondary for the Pittsburgh Steelers
- OLB coach Keith Heyward left to become the DC for UNLV and is currently a Quality Control coach for the Las Vegas Raiders
- DC Tim DeyRuyter left to become the Oregon Ducks DC and is now the DC for Texas Tech
We have not heard of any plans or intentions to make changes to the Defensive staff heading into the 2024 season
