I think you go with Boldin, the Ravens will come out firing to prove that they arent as inept as the Jags made them look Monday night, and Boldin has been the primary target all year. Washington hasn't looked good since getting #1 corners on him, Indy isnt good, but there's a good chance that that game turns into a CJ2K show.
As for the RB's, neither option is too tantalizing, I would probably go with Torain who's going against the Bills, not Ravens. The Bills run defense isnt that good. MoMo is an okay option, but he's splitting time with Keiland, and the Broncos front 7 is pretty stout.
