That's an interesting question. And there are actually a few. Jon Kitna, Cowboys Kevin Kolb/Michael Vick, Eagles Matt Leinart, Cardinals Jeff Garcia (was with Raiders to start year) Not many, but those are a few varying degrees of starter quality QBs currently serving as backups. Seneca Wallace also has a career 60% completion percentage and a 25:14 TD:INT ratio. I think he'd make an ok starter, but he'd have to have good weapons and a solid running game. You'd only take those guys after at least 20-25 other guys disappeared off the face of the Earth. It depends on which QB you're talking about from that list. I consider Garcia to be the best on that list and there are currently 14 starting QBs I'd take over him (with three I'm not sure about in Sanchez, Stafford and Henne). With some of those QBs, I'd take Vick or Kitna over them, but not many. I still think Leinart can be a quality starting QB in the league and Kitna, if nothing else, could pull a Kerry Collins for a year or two, I think. As for the QBs I'd take over Garcia - Brady, Palmer, Roethlisberger, Flacco, Peyton, Schaub, Rivers, Eli, McNabb, Romo, Cutler, Rodgers, Brees and Ryan. Roethlisberger and Romo only because of their age. Warner's a possibility, but I'm not sure if this year's bad start is a sign that he's done.
