I forget who the Steelers are playing, but I like Maddox. Bulger has a chance for good numbers though at home against the Seahawks. Sure, the Rams are 1-5, but Bulger still has Faulk, Holt, and Bruce to throw to.
If Maddox is playing a cupcake defense, go with him. If not, I'd go with Bulger and take the chance.
