It'll cost more than you think to get Quinn, and that's IF he's available. Why would his price go down because of two games where the guy ahead of him didn't look very good?
And...I don't think he's available now. Most of the speculation so far is that Anderson could get benched for Quinn, not that Quinn will get moved. Anderson doesn't have a very long contract -- it wouldn't kill them to cut ties after this season (or soon, at least), iirc.
My best guess -- wait a couple games, Anderson will improve. (He had a TOUGH weather situation in the last game. Don't underestimate how bad the wind will make you look.) Then, hopefully, the Browns start thinking about dealing Quinn (probably in the offseason, though). Maybe the price drops, but I've always been a fan, and I think he's worth a 1st. If you can get him for less, hallelujah.
