With Robert Saleh officially leaving the San Francisco 49ers to become head coach of the Tennessee Titans, Kyle Shanahan is once again tasked with replacing his defensive coordinator — the fifth change in as many seasons.

We break down external candidates like Brian Flores, Jim Schwartz, Raheem Morris, Matt Burke, and Corey Undlin, along with internal options including Gus Bradley, KJ Wright, and Daniel Bullocks. From aggressive blitz packages to conservative Cover-3 systems, we analyze scheme fit, roster impact, and long-term stability.

Plus:

• Why Flores might be the best defensive coach in football — and why it’s risky

• Which candidate best mirrors Saleh’s “All Gas, No Brakes” mentality

• Why continuity may matter more than upside in 2026

• How Saleh’s Titans job could impact the 49ers’ roster

If you’re wondering who should replace Robert Saleh, this episode has you covered.
