Wow. You're in deep crap, man.
You could take a risk and use Warner, because he was putting up lots of passing yards early in the year, but he fumbles and throws INTs, too, so you could run into the scenario where he throws for 300 yards, but fumbles twice and throws 4 picks, giving you negative points. He's a paradox, all right.
You could play Sparky Holcomb and hope that he gets into a shootout with Green... . What am I saying!?!?
Pete, you're screwed. Go with Dilfer and hope that they are getting blown out so he has to chuck it up there plenty and often.
