David Carr has left the building. He met last night and today with team officials but went back to his hotel around 2:30 p.m. this afternoon. Now the courtship stage moves into the negotiation stage between Carr's agent and the 49ers' chief negotiator, Paraag Marathe. The 49ers had scheduled a quick media session with Carr - at 12:30 p.m. - but that was canceled by Carr's camp. The 49ers clearly want Carr to be the top backup to Alex Smith. Carr, however, has options. The Cardinals and Browns also are interested in him and the Giants would like to retain him.
