San Francisco 49ers defensive coordinator Robert Saleh has been here before.
In the wake of historically bad injury attrition, including some on his own side of the ball, Saleh's 2020 defense ended up being a primary reason the Niners were even remotely competitive over the course of that forgettable season. While San Francisco's 390 points allowed on the year ranked 17th in the league, the total yardage given up (5,030) was fifth best. And that was in spite of losing key figureheads like defensive end Nick Bosa for nearly the entire year.
One could make the argument that campaign helped Saleh land his head-coaching job with the New York Jets the following offseason.
