The San Francisco 49ers have stayed relatively lucky in the retention of their assistants under head coach Kyle Shanahan the past couple of years.
True, the Niners lost their defensive backs coach and passing game coordinator, Joe Woods, to the Cleveland Browns’ defensive coordinator job during the offseason. And with a new rule in place, preventing teams from blocking other squads from prying away assistants in would-be promotional coordinator roles, Shanahan could have a tougher time retaining his staff’s continuity in 2021 and beyond.
Successful teams often prompt other teams’ interest in assistants.
