Re-setting the cornerback/safety market

If you're hoping your NFC North teams adds a cornerback and/or safety, you'll want to review ESPN.com's redesigned and now updated Free Agent Tracker for some context on a series of moves Friday that added significantly to a marketplace that in essence opens in a matter of hours.

Our guys at Scouts Inc. now rate Chris Gamble, released by the Carolina Panthers, as the top cornerback available in free agency. Another veteran cornerback without a team is Aaron Ross, who was let go by the Jacksonville Jaguars.

Meanwhile, two starting-caliber safeties were released Friday as well: The Arizona Cardinals' Adrian Wilson and the Jaguars' Dawan Landry.

With Louis Delmas set to test free agency, according to Dave Birkett of the Detroit Free Press, the Lions would seem to be in the market for a safety. The same could be said at cornerback if they do not re-sign Chris Houston. A safety wouldn't be a bad idea for the Minnesota Vikings or Chicago Bears, either.

Remember, teams can start negotiating with pending free agents (or, at least their agents) after midnight tonight. No deals can be official until Tuesday. We'll keep you updated.
