The Rams brought back another former Coliseum resident Friday when they signed free-agent cornerback Nickell Robey-Coleman, a former standout at USC.

Robey-Coleman played with receiver Robert Woods, both at USC (2010-12) and for the Buffalo Bills (since 2013). Woods signed with the Rams last month as an unrestricted free agent, and Robey-Coleman followed, after he was released by the Bills last month.

Robey-Coleman went undrafted in 2013, likely in large part because of his size (5-foot-8, 165 pounds), but he signed with Buffalo and made the active roster that fall.

In four seasons, Robey-Coleman appeared in all 64 games and started 15. He had three interceptions, including one last season against the Rams. Robey-Coleman returned it for a touchdown at the Coliseum.

Robey-Coleman likely will provide cornerback depth for the Rams, and fit in mid-pack among Trumaine Johnson, E.J. Gaines, Kayvon Webster, Lamarcus Joyner, Mike Jordan, Troy Hill and Blake Countess.

The situation could change though. Joyner likely will get reps at safety during the Rams’ offseason program, which begins Monday, and Johnson has been the subject of trade talks. The Rams also might select a cornerback with one of their picks in this month’s draft.

If Joyner moves to safety full-time, Robey-Coleman would be a strong candidate to replace him as the Rams’ slot cornerback.
