I have Vick and Big Ben/Stafford right now, and I'll probably throw out some trade offers, but I'm not desperate to move Vick. I don't understand the whole "he's only faced bad defenses, and he's about to face a gauntlet of shut down defenses" argument. Sure he faced Detroit and Jacksonville, and GB wasn't "prepared." However, no one else torched Jacksonville for as much as Vick did (Orton and Rivers are the other two QBs), Favre didn't torch Detroit at all, and Cutler put up similar numbers as Vick did against Detroit. His upcoming games are Washington and SF, who don't exactly inspire fear anymore. Washington gave up huge games to Bradford and Schaub, and SF has let Hasselbeck, Brees, and Cassel smoke them. In addition, I'm not really that afraid of any of the divisional rivals, except maaaybe Dallas's D, who held Schaub in check but couldn't contain Cutler. The giants and redskins aren't that good.
I don't think Vick will continue being the #1 quarterback, but I also don't think he'll fall off a cliff. In my eyes, he's a top 10 QB who has the obvious potential for huge games where he is the #1 scorer certain weeks. He's still got amazing weapons, and is mobile enough to get a few runs and avoid some sacks.
