FLOWERY BRANCH -- Falcons cornerback Robert McClain has drawn interest from four teams during the league's official "tampering" period.

The Dolphins, Saints, an NFC East team and AFC North team have expressed interest in McClain, who's been the Falcons primary nickel back over the past two seasons.

McClain beat back challenges from Josh Wilson and Javier Arenas to win the nickel back position last season. He ended the season as a starter after Robert Alford went down with a broken wrist.

He played in all 16 games and made six starts, but with the team shifting to bigger cornerbacks, McClain appears set to test the free agency waters.

The skinny: Unrestricted free agent.

The snaps: He played 642 snaps last season and was the 57th rated cornerback in the league who played at least 50 percent of his team's snaps, according to Pro Football Focus.

The stats: Receivers caught 67.1 percent of the passes with McClain in coverage. Quarterbacks has passer rating of 88.5 when throwing at McClain.
