Rams fire defensive coordinator Tim Walton

ST. LOUIS -- The St. Louis Rams fired defensive coordinator Tim Walton on Wednesday after finishing in the middle of the pack in his one season.

Coach Jeff Fisher, who said after the season that he didn't anticipate any coaching changes, announced the move and wished Walton well. Walton spent four years as secondary coach in Detroit before he was hired last year by the Rams.

The Rams didn't have a defensive coordinator in 2012, Fisher's first season with the team, after Gregg Williams was suspended for his role in the New Orleans Saints bounty scandal. Williams is on the market. He was a senior assistant on defense last year for the Titans, who fired coach Mike Munchak, and was defensive coordinator under Fisher in Tennessee from 1997 to 2000.

The Rams were third in the NFL with 53 sacks and finished with the 15th overall defense, allowing 345 yards a game. They were 13th in points allowed (22.8 average). The team finished 7-9, but was just 1-5 against the rest of the NFC West.
