I'm not going to go deep into your list (I specifically disagree with Cassel) but I would even add Nick Foles.  In the Washington game, Foles proved himself to me that he could be a solid QB in the league.  He stuck in the pocket, played through an injury and made some solid decisions for the most part.  I would also include him over Tebow.  So essentially, the entire NFC QB's I'd take over him.  That's pretty damning to Tebow as a QB, where you could say you would rather have an entire conference of QBs before one player.
