Restricted free agent CB Kevin Dockery is visiting the St. Louis Rams, according to this report from Pro Football Talk. Adam Schefter reports the same thing. 

Dockery plays Spagnuolo's style of physical, man coverage well. He's been mostly a nickel corner with the Giants, including the two years Spags spent there as defensive coordinator. This could be a good add for the Rams, upgrading their nickel spot between a healthy Bradley Fletcher and Ron Bartell, and making a decent replacement should one of those guys have to miss some time.

This continues the Rams theme of upgrading their depth via free agency, a smart course, if rather unsexy. 

Dockery was not offered a RFA tender by the Giants.
