Mike Singletary, a former teammate of Jeff Fisher in Chicago, is the latest known candidate to interview for the still vacant Rams’ defensive coordinator position. According to league sources, Singletary actually interviewed with Fisher on Thursday.
Former Cleveland Browns defensive coordinator Dick Jauron interviewed with the Rams at the end of Super Bowl week, or a few days after former Dallas defensive coordinator Rob Ryan dropped out of consideration for the Rams’ job.

Ryan was hired by New Orleans as the Saints’ defensive coordinator on Saturday, meaning the Rams’ now have the only unfilled defensive coordinator position in the NFL.

At first blush, the Rams’ interest in Singletary is curious because he has never been a coordinator and he’s not really known as an Xs and Os guy. Singletary, 54, has been special assistant to the head coach/linebackers coach in Minnesota for the past two seasons.

Prior to working with the Vikings, Singletary was head coach in San Francisco for parts of three seasons. He went 5-4 in 2008, taking over for Mike Nolan on an interim basis in late October. Retained by the 49ers after the ’08 season, the 49ers went 8-8 in 2009.

But Singletary was fired with one game left (the team was 5-10 at the time) in the 2010 campaign following a 25-17 loss in St. Louis the day after Christmas.
