NFL free agency rumors: Walter Thurmond signs with New York Giants

The cornerback market thinned out a little further Sunday morning as arguably the top nickel back option signed. Adam Schefter is reporting Walter Thurmond has signed with the New York Giants. The San Francisco 49ers brought in Thurmond for a visit, but he left without signing a contract, as he was mulling over his options. His mulling is complete and he is headed to the NFC East on a 1-year contract.

The 49ers did address the secondary when they signed cornerback Chris Cook, but if they head into the season with nothing more than this current group of cornerbacks, I'd imagine we'd all be pretty surprised. The 49ers secondary depth chart currently stands as follows:

CB: Tramaine Brock, Eric Wright, Darryl Morris

CB: Chris Culliver, Chris Cook, Dax Swanson

The team has 11 draft picks, giving them flexibility to move all around the draft board for the guys they want. They could move up to grab Justin Gilbert or Darqueze Dennard, or if they see cornerback talent sliding down, maybe they move back and turn 2014 picks into 2015 picks. They don't have to do one specific thing with their first round pick, but at some point they need to come away with some cornerback talent. We'll see how the 49ers approach it.
