It's possible Rodgers-Cromartie will be out of their price range, and he met with the Jets on Saturday, so there's competition. The Giants believe they could go with Prince Amukamara and Trumaine McBride as their outside starters if they don't sign anyone else, especially now that they have Thurmond to play the slot corner position that Terrell Thomas handled for them in 2013.
The Giants never seemed interested in bringing back Thomas and never made him a contract offer. Instead, his job goes to Thurmond, who will be 27 when the season starts and fits the age-range profile of the free agents the Giants have brought in this past week. Thurmond was the Seahawks' primary slot corner in their just-completed Super Bowl championship season and played well there. Pro Football Focus says his 0.85 yards allowed per snap in slot coverage was the fifth-lowest number in the league.
The Giants continue to look to fill holes in the secondary, the defensive line, the offensive line and at wide receiver and tight end as free agency rolls along into its second week. The Thurmond move will look better if they end up signing someone else for the outside who's an upgrade over McBride, but the slot corner position is effectively a starting position in the NFL today because of the proliferation of three- and four-receiver sets among offenses, and the Giants just nabbed a good young slot corner with a Super Bowl ring.
