Returning defensive coordinator Robert Saleh said his loyalty to the 49ers is a product not just of the chance they initially provided him in 2017 but of how they stuck by him when his first two years as coordinator didn't go well.

Saleh was the 49ers' defensive coordinator in 2017 and 2018. San Francisco's defense struggled in both years, finishing 25th and then 28th in scoring. But the 49ers enjoyed a vast improvement in 2019 (No. 8) en route to the NFC title.

Returning 49ers defensive coordinator Robert Saleh shared his philosophy and his goal in the role: staying well ahead of the offensive trends.
