Well this makes it a bit more interesting, since there are already players off the board. I'd say that at least the following will be keepers: Holmes, LT, Portis, Ahman Green, S. Alexander, R. Moss, Manning, Culpepper, Jamal Lewis, Edge, Harrison, Fred Taylor, Stephen Davis, Vick. Maybe Torry Holt, Faulk, Corey Dillon. I'm not sure how many people are in your league, probably 10 or so.
I guess I'll stick with my original opinion of keeping Robinson or Rodgers, although I guess keeping Moss would be a fine option too. Just remember that you will be lucky to get a top-tier guy, because most of them will already be taken before the draft even starts. If it were me, I'd probably take a good QB with my first pick, unless there was a top-tier RB left somehow. Of course this is all speculation and I probably have no idea what I'm talking about.
