The Lions may have another coaching position to fill this offseason. Defensive backs coach Tim Walton is interviewing for the Rams' defensive coordinator opening, according to the St. Louis Post-Dispatch. The Rams interviewed Walton last year to be an assistant defensive coordinator/passing game coach, but he chose to stay with the Lions. Could a coordinator position be enough for head coach Jeff Fisher to lure him to St. Louis? Walton has coached the Lions secondary since 2009, his first NFL job after more than a decade coaching in college. Although he's had a dearth of talented defensive backs, Walton has had success developing players in Detroit, most notably turning cornerback Chris Houston into a solid No. 1 option. And last season, the Lions secondary exceeded expectations early in the year despite several injuries and constant lineup shuffling, though the group struggled significantly during a season-ending eight-game losing streak. Walton, who was reportedly in St. Louis on Monday, would be the fifth Lions assistant to leave this offseason after the team chose not to re-sign three others and special teams coordinator Danny Crossman left for Buffalo. The Rams have also interviewed former Cleveland defensive coordinator Dick Jauron (a onetime interim head coach for the Lions) and Mike Singletary, Minnesota linebackers coach/special assistant to the head coach, for the vacancy.
