Signed veteran cornerback @triplcarr to a one-year contract today.

The Chargers weren't going to be able to defense the New Orleans Saints' spread offense, with their many receivers, with just 3 healthy Cornerbacks. They knew that, and brought in veteran Chris Carr (last seen on the Minnesota Vikings in the preseason) as the team's 4th CB.
No word on what the corresponding roster move will be, but there has been rumblings that Nate Kaeding might be headed to the Injured-Reserve list with his groin injury.
From the Chargers:
"Chris is an experienced player," said Head Coach Norv Turner. "I was fortunate to be with him for a couple years in Oakland. He's played at a high level in this league. He's been a starter so he brings experience. He can play in the slot and on the outside. He's a good addition for us."
