As NFL free agency heads into its second week, the wait continues for the Rams to sign their first free agent from another team.
Quarterback Shaun Hill of Detroit completed his visit to Rams Park on Tuesday and headed home without a contract. But the parties continue to talk and it’s possible there could be a deal today. Besides, home isn’t far away for Hill. An avid fisherman, the Kansas native resides in the Lake of the Ozarks area. He can be back in St. Louis pretty quickly to sign a contract.

But the Rams continue to be rebuffed when it comes to the interior of their defensive line. First, it was Houston free agent Antonio Smith who had a visit scheduled with the Rams but ended up signing with Oakland.

On Tuesday evening, Chicago free agent Henry Melton tweeted that he was joining the Dallas Cowboys. Melton had been scheduled to visit St. Louis.

Melton, a 2012 Pro Bowler with the Bears, missed all but three games of last season because of a torn anterior cruciate ligament in his left knee. After losing defensive tackle Jason Hatcher in free agency, the Cowboys were desperate for help on the interior of the their defensive line.

Dallas is a natural draw for Melton because he’s from that area, and Cowboys defensive line coach Rod Marinelli was on coach Lovie Smith’s staff in Chicago during Melton’s first four seasons with the Bears.

Melton was not guaranteed to start in St. Louis, where the Rams are happy with starting defensive tackles Michael Brockers and Kendall Langford but are looking for a third defensive tackle in their rotation, particularly one with pass-rush skills.

Buffalo free-agent defensive lineman Alex Carrington remains a possibility for the Rams. The team has yet to schedule a visit with Carrington, but that could change now that Melton no longer is an option. Carrington, 6-feet-5, 301 pounds, suffered a thigh injury and missed the final 13 games of 2013.

The Arkansas State product appeared in 44 games over four seasons with Buffalo, including nine starts. He has four career sacks.

So far the Rams’ only signings in free agency have been the re-signing of offensive lineman Rodger Saffold and outside linebacker Jo-Lonn Dunbar. And the Rams got Saffold on the rebound, when his deal fell through in Oakland after a failed physical.
