Former 49ers coach Mike Singletary wants to be a head coach again. Since he’s currently a linebackers coach with the Vikings, becoming a defensive coordinator would be a big step in that direction.

According to Jeremy Fowler of CBSSports.com, Singletary has interviewed for the defensive coordinator position in St. Louis.

Of course, Singletary became the head coach in San Francisco without ever being a defensive coordinator. To date, it’s a job he’s never held.

The Hall of Famer launched his coaching career in 2003, and he joined the Vikings in 2011. Last month, Singletary interviewed for the head-coaching job in Chicago, where Singletary played.
