Suppose Raheem becomes a HC somewhere this off-season and the Chargers fire Staley.
The Chargers defense looks SO BAD this year. It’s ok until they blow coverage and allow a 40-yard run.
Do you think he could do a good job again if he just focused on defense?
In your hypothetical scenario, yes. Absolutely. He is a good defensive coordinator. Some people are meant to be head coaches, some aren’t and Staley wasn’t. But he’s still very skilled when it comes to coordinating a defense when that’s his sole focus and he doesn’t have 100 other jobs like head coaches do. Look no further than Matt Nagy. He was horrendous as a head coach. But he’s back as a coordinator in Kansas City and doing alright as far as I can tell. Plenty of failed HCs do just fine as other types of coaches in the league.
