A month after he was released by the Texans, David Carr agreed Friday to a two-year deal to play for the Panthers. Carr, the No. 1 overall pick in the 2002 draft, will serve as Jake Delhomme's backup. "It's a case where we were obviously looking for someone to come in back up Jake and the opportunity to get a quarterback the caliber of David in free agency is unique," Panthers general manager Marty Hurney said. "We thought it was a good situation and a good opportunity for us."
