The Saints are considering signing a veteran quarterback to backup Drew Brees. ?We?ll see," said Sean Payton. "We?re a little restricted in regards to free agency signings or signings of unrestricted free agents in regards to the final four rule, but there?s still a lot of time here before we break, really a month. We?ll evaluate that. Whether we go to camp with three or not. I?d probably lean towards four if we could, but you?re limited with your camp numbers. We?ve taken three before to camp. We?ll keep looking at it and seeing how these younger guys are doing in the meantime.?
