How did those QB's fall of the face of the planet? Ok, maybe I'd agree with Dilfer, but he's still in the NFL. I'd have to disagree with Warner. He's gotten older, but he's still a good QB, and a starter. He could start on a bunch of teams in the NFL. Maybe people would hear of him more if he didn't play for the Cardinals, but they are an improving team.
Brad Johnson is older, but he could also start somewhere in the NFL. Maybe he could start on the Cowboys, but they have a soap opera type QB who's fans and teammates would rather blame losses on a girlfriend being at the games, then to fess up to getting outplayed.
